"Terrifyingly sad….Within These Walls creeps under your skin, and stays there. It’s insidious….The book’s atmosphere is distinctly damp, clammy, overcast, and it isn’t all the Washington weather: its characters’ souls are gray, dimmed by failure. Ahlborn is awfully good on the insecurities that plague both aging writers…and oversensitive young girls…which leave them vulnerable to those who…know how to get into their heads. So grim.”

– The New York Times Book Review

"Cruel, bone-chilling, and destined to become a classic, Within These Walls is worth the sleep it will cost you. Some of the most promising horror I've encountered in years."

– Seanan McGuire, New York Times bestselling author

“A monstrous Russian nesting doll of a book, holding secrets within secrets; the plot barrels headlong towards one of the most shocking climaxes you’re ever likely to read. This one’s going to wreck you."

– Nick Cutter, national bestselling author of The Troop and The Deep

“Ania Ahlborn is a great storyteller who spins an atmosphere of dread literally from the first page, increasing the mental pressure all the way through to the terrifying, chilling ending.”

– Jeff Somers, acclaimed author of The Electric Church and We Are Not Good People

"Ever-mounting terror and a foreboding setting make for pure storytelling alchemy....Ania Ahlborn goes for the gut with surprise twists that will stay with you for days. Not a book, or an author, that you'll soon forget."

– Vicki Pettersson, New York Times bestselling author
