This book covers Lister's life in the 1830s when she met and got to know Ann Walker. This account firmly identifies Lister as a butch lesbian but doesn't mention other options. A weird lack of attention to complexity. If you're not going to add anything and historicize, just print the diaries/letters. There's room for Lister to be an important historical figure for trans people and cis queer women, but this book is not interested in that.
