Waynoka and Mads have fled LA on motorcycles to get away from the effects of fire and drought, and have ended up in Wild West territory. Desperate for water, they go into a mine and there find a diary left by a woman who lived in the nineteenth century. While reading Lavinia's diary, Waynoka learns there are creatures that live in the mine.

This book had me so captivated the entire time I was reading it. The way it switched from the present to the past felt natural. Both timelines had an emphasis on found family which I really enjoyed reading. I look forward to reading more from this author.
