San Antonio is full of secrets, and seventeen-year-old Erasmo Cruz investigates the strangest of them. After gaining renown for surviving the city's legendary Ghost Tracks, he has set up shop as a paranormal investigator. But helping exorcize other people’s demons doesn’t seem to relieve his own; his best friend Rat has abandoned him, his grandmother is nearing death, and his own health has taken a sudden decline. None of these hardships can prepare Erasmo for the story his newest client brings him. Two decades after a strange ritual at a rural ranch, Bradley Erickson is being hunted by the Devil. In exchange for the life of his dreams, Bradley must surrender the blood of his child. The case hurls Erasmo into a dark web of cults, bargains, and broken pasts. Only one thing is certain: the Devil keeps his promises. "As frightening as it is fearless, The Devil's Promise pulls readers through unexpected and terrifying territory." —Johnny Compton, author of The Spite House "A wildly enjoyable horror adventure, The Devil’s Promise takes us into a world of demons, literal and figurative, that deftly examines the gruesome toll of playing with them. Riveting from the very first page to the last, Hurtado has written a book that demands to be devoured." —Gerardo Sámano Córdova, author of Monstrilio “With The Devil’s Promise , Hurtado hits the accelerator and doesn’t look back. A relentless story of the occult, lost souls, bargains, and ultimately, redemption.” —L.P. Hernandez, author of Stargazers "Creepy, gripping, and full of scares for readers of all ages, The Devil's Promise is destination reading for fans of The Exorcist , The X-Files , and horror fans at large." —Preston Fassel, author of Our Lady of the Inferno and Beasts of 42nd Street Praise for The Ghost Tracks "A wonderfully entertaining YA horror novel [that] inhabits the interstitial space between YA stories and full-blown adult literature about horrible things. A great reminder that one of the best things about horror fiction is its ability to twist our guts like a rollercoaster ride and make us ask for more." —Gabino Iglesias, National Public Radio “[A] riveting debut." —Carole Barrowman, Milwaukee Journal Sentinel “[An] indelible story that slowly sinks its teeth in and doesn’t let go." —Kirkus Reviews "Hurtado takes us on a journey of self-discovery that is unlike anything else you will find in a young adult novel." —Just Geeking By Celso Hurtado has been a punk guitarist, worked in the political arena, and played entirely too many hours of  The Legend of Zelda.
