When bestselling author Helen finds herself at the centre of a scandal, she escapes to Rathbrooke Hall on a remote island off the Northumberland coast. Tasked with cataloguing the books of a reclusive collector she's relieved to be out of the glare of publicity, even if the locals are less than welcoming. But as she spends more time among the dusty bookshelves and rare first editions, she uncovers clues to a secret collection of books that could save the island - and the community that she's begun to feel part of. Can she unravel the mystery of the hidden library and can she trust Thiago, a charming librarian with secrets of his own?
