This Is How You Lose the Time War

I just finished This Is How You Lose the Time War (2019) by Amal El-Mohtar and Max Gladstone. Lovely!

This was an epistolary novel with only two characters, Red and Blue, who write back and forth to each other. Apparently, Red's letters were written entirely by Gladstone, and Blue's by El-Mohtar. What a neat idea! (Note the colors of the authors' names on the cover.) I listened to the audiobook read by Cynthia Farrell and Emily Woo Zeller. Presumably, one reading Red and the other Blue (sadly, we don't get color-coded names of the readers).
