MILS (Man I Love Space). Lesbians in the 80s space race, need I say more??? Not only is this book one of the sweetest and simplest love stories, but it also inspired me to look into Sally Ride who I had no idea was part of the LGBT community!
You kind of forget that this book is urban fantasy halfway through because the main couple are so genuine and cute. The message about new-fatherhood is pretty straightforward but the horror is compelling throughout!
