This is an extraordinary and wondrous book, one that has altered my perceptions and to which I will return. Through a deeply personal dive into the life and scholarship of David Starr Jordan, Miller exposes the ramifications of hierarchical categorization of the natural while charting her journey through a crisis of identity. This is a profound and impressively researched story that is accessible for non-science readers as well as being beautifully written with humor and a sense of mission. Goes on my shelf of books that made me stop and rethink my beliefs.
