Returning overdue books has never been quite this dangerous.
Mercy borrowed a book to help her understand the fae. But when she tries to return it she finds the bookstore owner has disappeared and several nasty foes who wouldn't mind eating her. If only Samuel was feeling himself and someone wasn't trying to sabotage date night with Adam she could deal with this situation.
Despite their standalone nature, the plot of the books in this series overlap a lot. While you could jump into the series with Silver Borne and enjoy it without any problems, the significance and development of the plots would be a little incomplete if you hadn't read the previous instalments. That said, this novel feels like a turning point in the series, with Mercy starting to come into her own. Hard to comment without spoilers, and it really is just easier to read and enjoy.
