Standalone

Exo

"Dual timelines, a shockingly hyperdimensional setting, and flawed characters make this a must-read that recalls the work of Kim Stanley Robinson. Brush gives a familiar trope an original and exciting twist."

Library Journal, Starred Review!

"With a dual narrative, a twisty mystery, unusual science, and religious and political intrigue, Brush’s debut will find fans among both sf and mystery readers."

Booklist

"[E]arnest and detailed characterizations and worldbuilding mark Brush as a sci-fi writer worth keeping tabs on"

Publishers Weekly

"Colin Brush is a name to watch in the realm of speculative fiction. His breathtaking debut, Exo, emulates sci-fi greats like Kim Stanley Robinson and John Scalzi to explore themes of loss, coexistence, and human nature against the backdrop of a mesmerizing murder mystery. If you’re in the market for a thrilling whodunit with stratospheric stakes, don’t hesitate to give Exo a go."

Bookstr

"[I]t’s a haunting, slow moving book that you have to read slowly to ponder over... I enjoyed learning about the Caul, Mae and Sofria, and Brush’s prose, and the ending was satisfying!"

Takes Two to Book Review

"As well as engaging emotively, this is science fiction that challenges the reader to think. Readers are likely to come for the conceit of the Earth as a wasteland...but will stay for the emotional journey they embark on with Mae, Carl, and Siofra."
