A gang of thieves stage a daring heist from a vault deep below Princeton University’s Firestone Library. Their loot is priceless, impossible to resist.

Bruce Cable owns a popular bookstore in the sleepy resort town of Santa Rosa on Camino Island in Florida. He makes his real money, though, as a prominent dealer in rare books. Very few people know that he occasionally dabbles in unsavory ventures.

Mercer Mann is a young novelist with a severe case of writer’s block who has recently been laid off from her teaching position. She is approached by an elegant, mysterious woman working for an even more mysterious company. A generous monetary offer convinces Mercer to go undercover and infiltrate Cable’s circle of literary friends, to get close to the ringleader, to discover his secrets.
