I absolutely loved this book. Great characters, compelling plot, awesome level of historical and medical detail. This book is substantive and a super page turner as well. Donati is quite ambitious in this book. 
 This is a mystery, a medical procedural, a romance, a fictionalized reckoning with the horrible legacy of Anthony Comstock and the barbarity of forced reproduction, and a great analysis of late nineteenth century New York City mores. 
 This seems to be the first book in a series and it ends without definitively resolving its central mystery. I am a person who usually resents when authors leave dangling plot threads at the end of a book, but I had no problem with how Donati handled this book's ending. This book is almost impossible to put down once you start reading it and it feels completely satisfying as it is. I can't wait to spend even more time in this world with these characters. Drop what you're doing and read this now!
