The Lost Cube (Immortal Great Souls #4) audiobook review

Intro

The Lost Cube is Book 4 in Phil Tucker’s Immortal Great Souls series, presented as an Audible audiobook narrated by Nick Podehl and published by Podium Audio. Owner feedback on the listing clusters strongly around two consistent impressions: readers who’ve followed the series call this a continuation that delivers improved character work and rich worldbuilding, while a smaller set flags that parts of the plot feel like connective tissue building toward later books. If you’re shopping for a fan of progression-style fantasy who prefers listening (or enjoys reading along with audio), the listing and buyer feedback give a clear sense of what this install delivers—and where the gifting risk lies.

What it is / first look

At the simplest level the listing identifies The Lost Cube as an Audible Audiobook, authored by Phil Tucker, narrated by Nick Podehl, and published by Podium Audio. It’s the fourth entry in the Immortal Great Souls series; owner comments repeatedly describe it as a direct continuation that picks up after Book 3. The listing’s price fields are present on the product page, but this review does not quote those numbers; the format and edition are the key facts to check for a buyer.

Owners describe the book in series terms: it’s not positioned as a standalone; many comments assume familiarity with earlier entries and say that plotlines and stakes carry forward from previous books. One common owner phrase is that the plot “picks up right after Book 3,” which matters for gift suitability—this is most often enjoyed by people who have been following the series.

Who this is a good gift for

This is a targeted present rather than a broad, low-risk pick. Below are concrete recipient types and the conditions that make the audiobook a good match.

The ongoing series fan

• Why: Owners repeatedly call the series “amazing” and say the books keep getting better; Book 4 continues existing arcs and rewards prior reading.
• Assumption: Recipient has read Books 1–3 (or at least Book 3) and wants the next installment.

The progression-fantasy enthusiast

• Why: Multiple owners praise the series for progression-style storytelling, original worldbuilding, and character growth—qualities progression-fantasy readers often prioritize.
• Assumption: The recipient enjoys the genre’s tropes and the slower, long-form character progression that book-to-book arcs require.

The audiobook listener or commute multitasker

• Why: The product is listed as an Audible Audiobook and at least one owner specifically recommended combining reading and listening for an enhanced experience.
• Assumption: The recipient can access Audible-format audio or prefers listening to long-form fiction during commutes, chores, or workouts.

The gift for someone who loves strong worldbuilding

• Why: Owner feedback highlights “top shelf” worldbuilding, novel ideas about hell and sociopolitical complexity, and interesting new settings introduced in this volume.
• Assumption: The recipient values imaginative setting and explains why a continuing series world is worth following.

The cautious gift for a curious reader

• Why: If the recipient is open to a series rather than needing a standalone, Book 4 offers deep character arcs and escalating stakes that fans praise enthusiastically.
• Assumption: You’re comfortable that they won’t mind jumping in mid-series or will be willing to pick up prior entries.

In daily use

“Daily use” for an audiobook means how someone actually experiences it: listening sessions, chapter pacing, and how it sits alongside their routine. The listing labels this item as an Audible Audiobook; owners’ comments give the practical context you want before gifting.

How listeners describe the experience

• Engagement: Owners frequently say the book is “don’t-want-to-put-down” material or that they read it quickly—comments like “read it in two days” indicate high engagement for readers who also listen or read along.
• Narration: The listing names Nick Podehl as narrator, and at least one owner praises pairing audio with text as an “amazing reading experience.” That suggests the audio performance works well for at least some listeners.
• Pacing: Several owners praised the pacing and the way character arcs continue to evolve; however, a recurring counterpoint is that parts of the plot feel like set-up for future books rather than a fully self-contained payoff.

Best ways to use it

• Listen during commutes, chores, or while exercising if the recipient already uses audiobook services; the audio format is explicitly listed.
• For readers who enjoy both formats, consider gifting a text copy alongside the audiobook so they can read and listen simultaneously, a combination one owner recommended.
• Because this is Book 4, expect it to slot into ongoing reading sessions rather than serving as a clean single-night standalone book for someone who dislikes serial plots.

Materials & build quality

For an audiobook, “materials & build quality” translate to writing craft, plotting, and production/narration quality. The listing provides the author, narrator, and publisher; owner feedback fills in the rest about execution.

Writing and plotting

• Owner consensus on the writing is positive: reviewers call the series “phenomenal,” praise originality within the progression-fantasy space, and compare the author’s strengths in worldbuilding and character work favorably to major names in the genre.
• Strengths called out repeatedly are character development—secondary characters are said to “blossom” during this volume—and worldbuilding, with particular praise for provocative new locations and sociopolitical conflicts introduced in Silver Unfathom and beyond.
• Weakness flagged by owners: some sections feel like connective tissue for future books; one or more owners describe the plot as relatively “lukewarm” or “a build-up.” That’s not a universal view, but it’s a repeated caveat to weigh when you gift.

Narration and production

• The listing lists Nick Podehl as narrator and Podium Audio as publisher—concrete production credits the listing provides. At least one owner notes the audio pairing improves the experience and recommends the audiobook specifically, which suggests the narration and production quality are acceptable to many listeners.
• The listing does not supply technical details like runtime, bitrate, or file format beyond the Audible Audiobook label; if those are important (e.g., audiobook download strategy or device compatibility), confirm them on the current listing before purchasing.

Safety considerations

Books are low in physical safety risk, but there are still gift-relevant considerations—content sensitivity, age-appropriateness, and format accessibility are the practical touchpoints here.

• Content and tone: The product is categorized in the listing under Horror > Dark Fantasy and Literature & Fiction. Owner comments reference “hell,” battles, sociopolitical minefields, and escalating stakes—language that signals darker themes. The listing does not provide trigger warnings; check the seller/manufacturer page or sample content if you’re concerned about specific sensitivities.
• Age-fit: The listing does not state a recommended minimum age. Because the category includes dark fantasy and owners describe mature conflicts, this gift is safer for adult or older-teen readers who enjoy darker speculative fiction.
• Format access: The listing specifies Audible Audiobook format. Confirm the recipient’s ability to play Audible files or whether they have an account/platform to access audio versions; lack of access to the required audiobook platform is the most common practical gifting snag with audio editions.

Who should skip it

Not every reader will be pleased. Skip or rethink this gift if:

• The recipient dislikes ongoing series or prefers standalone novels—owner feedback emphasizes series continuity and threads that carry across books.
• The recipient avoids dark themes or horror-adjacent fantasy. The listing category and owner language point to mature, darker content.
• The recipient does not use Audible or cannot easily play the Audible audiobook format; the listing lists Audible as the format, and technical compatibility is not detailed there.
• You need a low-risk acquaintance gift. This is a better present for a known fan or someone open to serialized progression fantasy rather than a safe, generic pick.

Verdict

For fans who’ve followed Phil Tucker’s Immortal Great Souls or listeners who enjoy progression-style dark fantasy, The Lost Cube (Book 4) is a strong continuation with notable strengths in character growth and worldbuilding. Owner feedback is overwhelmingly positive about the series as a whole, calling it one of their favorites and repeatedly praising the way characters develop across installments. The primary trade-offs are that Book 4 sometimes reads like a setup for future books (a repeated owner caveat) and that gifting an Audible audiobook requires the recipient to have compatible means to play it.

Check before you buy

• Confirm the edition: the listing specifies this is an Audible Audiobook narrated by Nick Podehl; verify that you’re buying the audio format the recipient can use.
• Confirm series familiarity: many owners say Book 4 picks up right after Book 3—this is not positioned as a fresh standalone.
• Check audience fit: the listing is categorized under Horror & Dark Fantasy; if the recipient avoids darker themes, this may not be appropriate.
• Consider bundling: owners recommend reading while listening; pairing a text edition with the audiobook can be a nicer gift for someone who enjoys both formats.

Final verdict: Buy for the committed series fan or the progression-fantasy listener with Audible access; maybe for an adventurous reader who likes serialized, character-driven worldbuilding; skip as a safe pick for acquaintances who prefer standalone or light reads.
