HELP! Trying to find book I read, can’t find it.

I read this book on KU and I’m trying to find it again. It’s about this queen who is unhappy with her marriage. Her and her husband are the only people who never age (she had caught a fae and he granted her a wish for releasing him). Well now she’s unhappy and wants to have her marriage fixed. She ends up falling for the fae and so on and so forth. The author had her own drawings throughout the book and I wanted to re-read it but KU doesn’t save all the books you’ve read.
