Finalist for the NBA Irish Book Awards Crime Fiction Book of the Year
"I don’t say this lightly: A House of Ghosts is one of the best books I’ve read this year. . . . A House of Ghosts is a throwback in the best of ways. Ryan uses tropes and framework made classic by the likes of Christie and Sayers to crafta cunning, many-tiered story that, paradoxically, feels both fresh and familiar. This is a ghostly big house mystery that’s cozy and invigorating."—Criminal Element

"This unconventional historical mystery combines spies, ghosts, and wartime in a riveting Agatha Christie–type story that tells of the tragedy of a lost generation. . . . Seems designed for fans of Charles Todd’s 'Ian Rutledge' books."—Library Journal, starred review

"A ripping yarn . . . Agatha Christie fans will have fun."—Publishers Weekly

"Ryan pulls out all the stops. . . . There'll be séances, unmaskings, things that go bump in the night, voices from beyond the grave, and revelations of several different characters' unsuspectedly dark connections to the Great War. Throughout the alarums and excursions, the low-maintenance heroine maintains a composure that should serve her well in the promised series."—Kirkus Reviews

"A promising mix of supernatural and historical thriller."—Booklist

“A genre-blending fusion of old-school ‘big house’ mystery, romantic suspense, and spine-tingler. There’s plenty of conventionally spooky fun to be had—secret passages, apparitions and the like—but what gives this book real atmosphere isn’t so much the jump scares as the well-rendered pathos of a country struggling to come to terms with the loss of a generation.”—Guardian
