Claire North always breaks my brain in the best way possible. Their latest is an utter delight, introducing us to Cal, a gender-bending time traveller who hops centuries with ease, and Olivier, an honour-bound army officer on the cusp of the French Revolution. What begins as a simple love affair becomes a devotion that crosses millennia, invokes a deadly paradox that threatens the entire construct of reality, and draws the attention of a mysterious witch from the cracks of time itself. Casually brilliant, flippantly funny, deeply philosophical, and achingly tender, As We Fall Through Time is one of the best books of the year.
