Which novel by John Grisham was conceived on a road trip to Florida while thinking about stolen books with his wife?

The story behind the answer

Camino Island is correct because John Grisham has said he dreamed up the story during a road trip to Florida with his wife, musing about stolen rare books and a shady-but-charming bookseller. The novel opens with the heist of F. Scott Fitzgerald’s manuscripts from Princeton and follows Bruce Cable, a Florida beach-town bookshop owner who may be fencing the loot—melding Grisham’s legal-thriller instincts with literary caper flair.
