Summary

A debut sci-fi mystery set on an abandoned future Earth, featuring a twisty mystery straight out of a John le Carré novel, a group of larger-than-life characters who’d be at home in the work of John Scalzi, and a deeply weird and dangerous hyperdimensional entity to haunt the dreams of any reader of Kim Stanley Robinson.

Humanity is dying. Banished from the Earth, our descendants eke out lives in orbital habitats and moon colonies––and look with longing on our former home.

But…

What They're Saying

Critics Review

“Brush explores whether humanity should cling to its old home or seek a new life among the stars in this novel about a uniquely imagined dystopia… . 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 (SFF Debut of the Month, starred review)

“At the center of Brush’s turbulent debut is a rogue ocean, the Caul, on an ecologically compromised future Earth… . Brush keeps the pages turning with twisty conspiracy theories and exciting scenes of Mae wielding her survival skills with cinematic flourish, surrounded by the Caul’s ‘inter-dimensional’ quantum foam….the earnest and detailed characterizations and worldbuilding mark Brush as a sci-fi writer worth keeping tabs on.”
Publishers Weekly

“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

“[A] dramatic setting [that] will remind many readers of past stories with wastelands that hold mute phenomena at their heart. These include the Strugatsky brothers’ Roadside Picnic, and more recent works such as Jeff Vandermeer’s Annhilation. Or, with a more particular British flavour, the works of JG Ballard and Robert Holdstock’s Where Time Winds Blow … As well as engaging emotively, this is science fiction that challenges the reader to think. “
—Dev Agarwal, The BSFA Review
