This beautifully written book is nonfiction but it reads like a particularly gripping novel. It’s filled with natural history, scientific discovery, pharmaceutical developments, and plenty of politics, and yet, Sargent tells the horseshoe crabs’ tale with enormous compassion and balance.

The fascinating story of the horseshoe crab is a thought-provoking and sobering reflection on the unintended consequences of scientific progress and the dangers posed when self-regulating industries control a limited natural resource.
