"In this brilliant story, Oyebanji makes the reader question perceptions of guilt and innocence, of vengeance and justice, of time itself—all the while asking what makes us truly human. A tour de force and most highly recommended." —Julie E. Czerneda, author of To Each This World
"A tightly wound plot told from two divergent points of view that will keep you guessing in the best ways. If you're a fan of SF mystery, Esperance merges the best from both genres." — Michael Mammay, author of the Planetside Series
"A gripping, intricately plotted mystery which unravels its themes of justice, choices and consequence with huge assurance and flair" — E. J. Swift, author of The Coral Bones
“A police procedural genetically modified to include the best of science fiction, mystery, action, and suspense...this page-burner earns its moral heft.” —Donna Glee Williams, author of The Night Field
“A gripping mystery about an impossible murder combines with a marvellous story of a strange, possibly alien, odyssey around our present-day world, with all its problems and heritage. Guess the murder solution and you're a better reader than I, though the solution is both satisfying and resonant. Thrilling and sparky writing, extremely readable: a gem of a thriller.” —Adam Roberts, author of Lake of Darkness
