It's called Kill-Grief (Picnic Publishing, 2009) and it's written by Caroline Rance, who just happens to live almost 5,000 miles from me (as the crow flies from Texas to England) but has become a frequent and faithful correspondent, and friend.
I first became familiar with Caroline's work via her amazing website and blog at The Quack Doctor where she shares stories, illustrations, and information about the history of medicine, especially "panacean powders, pills, potions, procedures and pamphlets," which - as anyone who reads this blog knows - is right up my alley!
Caroline has also written a novel, Kill-Grief, and since I already admired the blogging she was doing, I just knew I had to read it! And I'm so glad I did!
Here is the description of the book from Caroline's personal website (here):
