"This is How You Lose the Time War" asks the reader to perch on the shoulders of two operatives on opposing sides of a time-traveling war.

Each chapter follows "Red" or "Blue" as they scurry up and down timelines and across dimensions. The book is both sweepingly broad and extremely contained and personal.

The settings flit by, dizzying: a temple for mechanized humans, an ancient holy cave, the assassination of Caesar - each sketched with broad, emotional strokes to give the setting an aesthetic. One gets the sense that a great web of cause and effect is being constantly constructed, altered, and destroyed, without ever seeing the full picture.

Against these backdrops, the characters "Red" and "Blue" write to each other - as nemeses, then as friends, ever deeper entangled even as they demolish each other's plans and forces. The letters make up an enormous part of the experience, and they are comic, intimate... poignant. I didn't give a damn about the war - I just wanted these two characters to be alright.

I loved it. I stayed up past midnight every day I was reading, which wasn't long because I had to see what came next and kept reading.
