"Chilling . . . Propulsive and un-put-downable."
--USA Today

"If you've never heard of Israel Keyes, his name will fill you with dread after reading Callahan's superb investigation of how such a monster managed to thrive in our modern world."
--Bethanne Patrick, The Washington Post

"A page-turning mystery."
--New York Post

"Riveting . . . American Predator is a fine book--exhaustively researched and candid without being prurient--that should be as illuminating to law-enforcement as it is fascinating to the general reader."
--Dennis Drabelle, The Washington Post

"A chilling and riveting read, it's a peek into the mind of a killer and the investigators who eventually tracked him down."
--Refinery29

"Callahan has produced a superb work of true crime writing that will haunt its readers long after the final page has been turned . . . A deeply frightening book."
--Anchorage Daily News

"An interesting, illuminating, and chilling account of a strange and lethal killer who baffled even the FBI's famed Behavioral Analysis Unit's profilers. . . . American Predator is a well-researched and well-written book about a modern monster and the law enforcement people who caught him and tried to understand him."
--The Washington Times

"Vivid . . . chilling . . . Callahan's portrait of this monster, and of the men and women who do their best to uncover his secrets, is one that will keep you up all night."
--Tampa Bay Times

"American Predator is the scariest book I've ever read. No exaggeration--the book you hold is bone-chilling. Maureen Callahan explores the black heart of a new kind of American monster--a serial killer that confounded our most elite criminal profilers--and the race-against-time investigation to follow. This is the work of a journalist in her prime, telling you the story the FBI doesn't want you to hear and delivering an unforgettable tale of evil that will haunt you. Mark my words: This modern true crime classic will stand with the likes of Jeff Guinn's Manson, Ann Rule's The Stranger Beside Me, and Michelle McNamara's I'll Be Gone in the Dark."
--Susannah Cahalan, New York Times bestselling author of Brain on Fire

"Wow! American Predator is excellent and it is terrifying. Maureen Callahan's deft reporting and stylish writing have created one of the all-time-great serial-killer books: sensitive, chilling, and completely impossible to put down."
--Ada Calhoun, author of St. Marks Is Dead

"I started American Predator late at night and grew terrified just a few pages in--yet I could not put it down. Through deep interviews with FBI special agents and newly uncovered documents, Maureen Callahan crafts a chilling and unforgettable portrait of a singularly cunning killer and the diverse members of law enforcement he strove to outwit. Read it as soon as possible--in daylight."
--Karen Abbott, New York Times bestselling author of Liar, Temptress, Soldier, Spy and Sin in the Second City

"Prepare to lose sleep. Prepare to skip meals. Maureen Callahan delivers a masterful telling of the monster who threatened a nation. Spellbinding and unforgettable."
--Adam Makos, New York Times bestselling author of Spearhead

"An extensively researched and well-written account of a unique serial killer. . . . I commanded the Bronx Homicide Task Force, I have worked homicide investigations, I continue to consult on cases and have trained nearly 75,000 professionals in practical homicide investigation. . . . I highly recommend this book."
--Vernon J. Geberth, author of Practical Homicide Investigation

"A riveting true crime saga . . . . The 21st century's most meticulous serial killer baffles investigators with his forethought and ruthlessness in Maureen Callahan's riveting true crime narrative."
--Shelf Awareness

"A deep dive into the twisted life of Israel Keyes, 'a new kind of monster' . . . Serial killers often commit their crimes close to home, inside a comfort zone, but as the author documents throughout this compelling narrative, little about Keyes fit the conventional serial-killer mold . . . [Callahan] offers fascinating context about law enforcement investigative techniques and revelations about how a murderer can strike again and again without being detected for more than a decade."
--Kirkus

"Investigative journalist Callahan provides a chilling true-crime narrative in this detailed study of Israel Keyes, whom she describes as 'a new kind of monster, likely responsible for the greatest string of unsolved disappearances and murders in modern American history.' . . . Through Callahan's access to many of the key players in law enforcement, she has produced the definitive account of a terrifying psychopath."
--Publishers Weekly (starred review)

"A riveting, propulsive account of a highly intelligent serial killer who skillfully evaded capture for years. . . . Callahan recounts the story with a deft touch, blending multiple sources, including his court psychological profile, into a seamless narrative. . . . Gripping and superbly researched, this is destined to be a true crime classic, alongside titles such as Vincent Bugliosi's Helter Skelter. And to readers who enjoyed Michelle McNamara's I'll Be Gone in the Dark: One Woman's Obsessive Search for the Golden State Killer."
--Library Journal (starred review)

"Keyes is terrifying, and his crimes horrific, but Callahan's focus on the FBI's attempts to learn about his other crimes makes for a truly edge-of-your-seat page-turner even without the "hunt." A must for fans of Mindhunter--both the book and its recent Netflix adaptation--and the long-running police drama Criminal Minds."
