Roth knows how to write. So even though this second book of the trilogy that began with Divergent feels like a necessary bridge between the haunting story she created in book one and the hinted-at chaos of book three, readers will be quick to forgive. Tris, reeling from the loss of her parents and guilt-ridden over having shot her best friend, must escape the Erudite faction’s horrific takeover by fleeing first to Amity and then Candor. Reluctantly, she joins forces with the “factionless” to defeat Erudite. As stubborn and self-destructive as ever, Tris butts heads with Tobias and tests everyone’s (perhaps even readers’) patience. Roth keeps every chapter action-packed, moving Tris tantalizingly close to learning the secret her parents were fighting to unleash. The author has a subtle way of pulling readers into a scene (“The outside air.... smells green, the way a leaf does when you tear it in half”), and the novel’s love story, intricate plot, and unforgettable setting work in concert to deliver a novel that will rivet fans of the first book.
