Schwab, V. E.: The Invisible Life of Addie LaRue

Addie La Rue has learnt the hard way that deals with the devil are tricky things. Immortal but eternally invisible and forgotten by people, Addie exists only as a muse for artists throughout history. The only person who remembers her is the devil, who visits every year on the anniversary of their deal. Until one day, in a bookshop in New York, she meets a boy who remembers her.
