Empire of the Summer Moon

Gwynne’s history of Comanche power on the southern plains — a horse empire that stopped Spanish, Mexican and then American expansion for over a century — told alongside the life of Quanah Parker and his captive white mother.

Why it’s on the list: Named in the replies to @typesfast asking for the best history book you’ve read — a crowd-sourced list Kyle recovered by hand and saved. Kyle’s line notes it came up twice in that thread.

Kyle’s line reads “Empire of the Summer Moon (twice)” — two separate people in the same thread named it. recommendation_count stays at 1 because it is one thread.

Where I saw it: In the replies to @typesfast asking “What’s the best history book you’ve read?” (June 5, 2025). Kyle recovered the reply list by hand and saved it to his “Books To Read” Apple Note; the full transcribed list lives on What’s the best history book… (tweet).
