PRAISE FOR UNCERTAIN SONS

"You! Yes, you! You need this book! The stories in Uncertain Sons already feel like classics of the uncanny. As inventive as Ray Bradbury, as unsettling as Thomas Ligotti or Carmen Maria Machado, Ha knows how to produce that peculiar, pleasurable, creeping sense of wrongness and dislocation so particular to weird horror. I am such a fan of Thomas Ha's writing-and I expect that you will be, too." -Kelly Link, Nebula, Hugo, and World Fantasy Award-winning author of The Book of Love and Get in Trouble

"Thomas Ha's first collection, Uncertain Sons and Other Stories, offers a unique voice and stylistic range. Engaging characters in believable yet off kilter realities will remind readers of their own lives. One of the very best new collections I've seen in a while. -Jeffrey Ford, Author of A Natural Historyof Hell and Crackpot Palace

"A devastatingly good book of stories. Thomas Ha offers glimpses of weird worlds that continue to bubble and spread in your mind long after you finish the stories, slowly seeping into every crevice of your brain. This is a collection I wish I'd written. This is weird horror at its very best." -Brian Evenson, Author of Good Night, Sleep Tight, and The Glassy, Burning Floor of Hell
