“This excellent SF-thriller opens with Ethan Krol looking at three beings on the floor of his twentieth-floor Chicago apartment: a man, his son, and a barracuda…Fans of Charles Stross’ near-future police procedurals will be drawn to this one.” — Booklist (starred)
“Lovers of sharp, fast sci-fi from the likes of Neal Stephenson will be right at home with Esperance. For this reader, it scratched about a dozen itches at once and then some. It’s exciting, inventive and murky, an ocean worth the plunge.” —BookPage (starred)
“This mixture of mystery, SF, and historical fiction is highly recommended for readers who love intricately blended genre stories that ask big questions. Those who fell hard for Rivers Solomon’s The Deep or Leslye Penelope’s Daughter of the Merciful Deep will find a kindred story here.” — Library Journal (starred)
“Adam Oyebanji mixes the traditional trappings of a detective novel with science fiction tropes and adds his own Afrofuturist-inspired notes to create something fresh. Esperance is an engaging read because of the way Oyebanji blends these genres, as well as the thrill of learning who is behind the murders – and why.” — Locus
“[D]extrously blends genres in this suspenseful sci-fi mystery…. Rob Hart and Blake Crouch fans should check this out.” — Publishers Weekly
“A fast-paced, superbly plotted blend of mystery and science fiction” — The Guardian
“In Esperance, critically acclaimed writer Adam Oyebanji boldly combines the genres of murder mystery and science fiction to produce a compelling novel—which alone is no easy feat—that explores social structures and cultural history.” — Science Magazine
“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
