The Physick Book of Deliverance Dane - Katherine Howe Here's the main problem with this book: The main character, someone who specializes in the time period the book is supposed to be from, doesn't know that "receipts" means "recipes". WTF? I mean, I am no historian, and I KNEW THAT. It takes her almost the entire book to figure this out, despite it being fairly common knowledge. Unbelievably stupid. This is not the only example of things the protagonist would have figured out if she had been the person the backstory claims her to be. Just ridiculous.
