There is no hand-holding from Peters here as she takes us into the complex web that connects Reese, Ames, and Katrina as they navigate sexuality, gender, their own traumas, and parenthood in the twenty-first century. The plot centers around Ames, a detransitioned transgender woman, who comes to his ex-girlfriend Reese, a trans woman, with a proposal: to be a third parent to the child he and his boss Katrina are bringing into the world. As the story jumps back and forth through time, we are privy to how the characters grapple with their own identities and the complexity of existing as transgender women. Detransition, Baby is a sharp debut novel that is at once thought-provoking and tender, a grounded view of new understandings of family.
