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!"
