**STARRED REVIEW** Leviathan Falls picks up where Tiamat’s Wrath (2019) left off: the Laconian Empire defeated, Teresa Duarte onboard the Rocinante with Holden and crew, and the ancient enemy of the gate builders seeking ways to destroy reality itself. The final installment of Corey’s Expanse series is its strongest yet. It’s a thrill ride of a tale, boasting the same kinetic momentum of the first book, with the highest possible stakes and profound emotional resonance. The story is masterfully paced and structured, filled to bursting with some of the genre’s best world building. One of the central themes is how individual selfishness sabotages the greater good. It’s easy to read this as a commentary on current real-world circumstances, but it is elevated into an exploration of universal truths. This book illustrates the greatest strength of speculative fiction: to imagine unique circumstances as strange mirrors to help us see ourselves more truly. Corey maintains an impressive balance between unflinching realism and hope, with no illusions about the myriad faults of humanity, but still holds a fundamental belief in the essential worthiness of people. This is a deeply satisfying and fitting conclusion to one of the best space opera series in many years.
