Ritual summoning at the public library is NOT on the list of preapproved events. On a tiny island off the coast of New England, in an old Victorian mansion, there is a library in need of a live-in librarian. The job is perfect for Olivia, so she happily drops everything to take the ferry out to Cat Island and start a new life. She doesn't care that the population of the island is small enough that she has no chance of a social life. She has what she needs: a place to stay, books, and maybe even a mystery to solve. From the day she arrives, Olivia feels like she is not alone here. Someone seems to be trying to make contact, through books and bells, sending playful messages. She's not sure she believes in ghosts, but she can't shake the feeling this all must be connected to the portrait of the melancholy young man that hangs in the rare books collection. Olivia is determined to discover her library's secrets, even as that search takes her far beyond moldy old archives and anything her library sciences classes prepared her for.
