Advent (The Exlian Syndrome Series, #1) by Seth Ring
A classic underdog progression fantasy set in an alien-invaded, superpowered society, Advent balances high-octane leveling action and military intrigue with accessible characterization—delivering fun genre comfort with notable, if sometimes frustrating, genre limitations.
Premise & Setting:
Advent introduces Mark Fields, a powerless dishwasher in a dystopian city perpetually at war with insectoid alien “Exlians.” Mark comes from a family of renowned heroes but, past the usual age for power manifestation, is left with little hope until a chance encounter with a dying scientist radically shifts his fate. Suddenly gifted with unusual powers, Mark enters a militarized training camp just as Exlian attacks and citywide conspiracies threaten everyone’s survival.
The city-centric world feels both vibrant and oddly claustrophobic (with little sense of a broader planetary society), and the premise borrows heavily from anime, cultivation, and military SF traditions. While the singular city focus adds social pressure and narrative clarity, it leaves some readers feeling the setting is underexplored or missing broader global stakes.
Progression Mechanics:
Ring’s take on progression fantasy (and LitRPG elements) lands in the “leveling, but not stat sheet-heavy” tradition. Mark’s powers and progression system are clearly explained, but Ring eschews excessive numerical detail and focuses on training montages, innovative use of powers, and the importance of teamwork. The book features vivid action sequences, creative alchemy, and “dream training” (a highlight for many readers) but remains more interested in creative power application and steady growth than crunchy stat optimization.
Where Advent rises above some of its genre brethren is its emphasis on Mark’s hard work and problem-solving rather than easy power-ups or overpowered antics from page one; the path to power is consistently incremental and, thus, more rewarding.
Characterization & Team Dynamics:
Mark is a classic “decent underdog”—earnest, hard-working, and, at times, believably insecure. Some readers find his voice a bit too “innocent” or adolescent, which fits the teen/early twenties protagonist archetype, although his emotional development occasionally lags behind plot developments. His journey from isolation to integration with a varied cast of companions is a core driver of the story’s emotional beats.
The ensemble includes highlights such as:
Pacing, Plot, and Structure:
Advent spends its first quarter rooted in manga and anime system-stories, but picks up the pace after Mark’s turn of fortune. Many enjoy the book’s action, the “team-building” intensity, and escalating tension as Mark is drawn into city conspiracies and waves of alien attacks. The focus on gradual mastery—rather than immediate world-shaking power—grounds the narrative, encouraging reader investment in both Mark’s and his team’s arcs.
A significant criticism is the abrupt, cliffhanger ending and a sense of plot “setup” over self-contained story. Key mysteries—why Mark’s brother’s group was targeted, the purpose of Mark’s powers, and political secrets about the Exlians and city elite—are only lightly touched on. For completion-seeking readers, Advent can feel like an extended pilot episode, promising more than it resolves.
Style and Accessibility:
Ring’s prose is clean, readable, and brisk—though some dialogue slips into cliché and telling, not showing. This accessibility makes the book a great entry-point for LitRPG and progression fantasy newcomers, and many highlight the successful audiobook narration as boosting enjoyment.
Comparative Analysis — Genre Contemporaries:
Criticism & Flaws:
- Dialogues and emotional depth can run shallow or generic; several reviewers hope for richer interpersonal engagement.
- The romantic subplot divides readers for feeling forced, undercooked, or lacking real connection.
- Pacing is uneven—sometimes setup-heavy, sometimes meandering with montage over action or discovery.
- Worldbuilding is incomplete—society outside the city and some institutional logic are left for sequels.
- Cliffhanger ending and lack of standalone arc can frustrate those seeking resolution.
Conclusion:
Advent is a solid, if sometimes predictable, entry into the LitRPG/progression fantasy landscape. Its underdog MC, reliable team dynamics, and satisfying (albeit tropey) leveling provide comfort for genre fans. While it doesn’t break major new ground, it avoids most big pitfalls and is more ambitious with politics and group dynamics than most debuts—though less developed in romance and world immersion. Recommended for readers seeking a fun, team-focused new series with growth potential; those looking for more literary polish or innovation may wish to look elsewhere.
Rating: ⭐⭐⭐✩✩ (3.0/5) — Enjoyable and comforting, with room to grow; a promising open salvo for the Exlian Syndrome series but not yet a genre standout.
