This is How You Lose the Time War
by Amal El-Mohtar & Max Gladstone (Simon & Schuster, 2019); audiobook read by Cynthia Farrell & Emily Woo Zeller (Simon Schuster Audio, 2019)
What seems at first a gimmicky homage to Spy vs. Spy turns out to be a serious piece of conceptual science fiction, greatly enhanced by the authors’ embracing of texturising vignettes within the time travel plot. Makes Philip K. Dick look ordinary.
