Duologies live or die by their conclusions, and Ruthless Vows does what the best second books do: it takes everything that made Divine Rivals beloved and burns it down in order to show what survives the fire. What survives, it turns out, is something more complex and more earned than the first book’s enchantment.
The War Gets Real
Divine Rivals kept the war at a certain aesthetic distance — the frontlines were where Roman was, a place Iris understood through letters rather than direct experience. Ruthless Vows closes that distance. Iris crosses into the warfront, and Rebecca Ross renders what she finds there with unflinching clarity. The mythology of divine conflict, the gods using human soldiers as game pieces, snaps into something with genuine moral weight. This is still a fantasy romance, but it earns its drama.
Roman Without His Memory
The novel’s central dramatic device — Roman’s memory loss, his altered allegiance — is emotionally ruthless in exactly the way the title promises. Ross is not interested in a quick fix. The Roman that Iris finds is not the Roman she lost, and she has to decide what that means for who they are to each other. The scenes where they circle each other, Iris knowing what he doesn’t, are some of the most quietly agonising in recent YA fantasy.
Iris Coming Into Her Own
The first book was partly about Iris discovering her voice as a writer. The second book is about her discovering her nerve. She takes risks here that would have been impossible for the girl she was in Divine Rivals, and Ross traces that development without ever making it feel unearned. Iris’s relationship to her own ambition — to her writing, to her choices — is the throughline that ties the duology together.
The Gods and What They Represent
Ross’s gods are petty, powerful, and fundamentally indifferent to the humans whose lives their war consumes. That indifference, and what humans choose to do in the face of it, is the philosophical spine of the duology. Ruthless Vows makes the stakes of that choice legible in a way the first book could only gesture toward.
Why YA Readers Will Love This
Ross has written a war story that takes seriously the cost of conflict while remaining fully invested in love as a valid and powerful force. The combination of romanticism and genuine darkness is the sweet spot that YA fantasy does better than almost any other genre. Ruthless Vows is unsparing, beautifully written, and satisfying in the way that only a story that was always heading somewhere definite can be. Have tissues ready.
