For his new book that centers on a rare book manuscript heist, John Grisham is doing a 12-stop book tour — his first extensive one in a quarter century.

JACKSON, Miss. — John Grisham fans will get a double treat in June — a new book and a 12-city tour, his first such extensive tour in a quarter century.

On June 6, fans will be able to get their hands on new thriller Camino Island, the first book he has done involving rare books and bookstores.

“The story came out of nowhere a couple of years ago, and the more I wrote the more I enjoyed it,” Grisham said. “It’s a fun trip through the murky world of stolen rare books with an ending that everyone has liked so far.

“I almost got through with the story avoiding all lawyers, but, alas, a couple were needed at the very end,” he said.

Grisham’s website has posted the rules for his book tour, which starts June 6 in Paramus, N.J., and ends June 29 in Doylestown, Pa. The tour is a combination of noted bookstores, such as Parnassus Books in Nashville, along with lesser-known bookshops, all of them east of the Mississippi.

On June 20, Grisham will stop at Square Books in Oxford, Miss., which Publishers Weekly named Bookstore of the Year in 2013.

By ordering ordering the new book on Square Books’ website, owner Richard Howorth said people will be entered for a drawing to become one of 200 who will be able to attend a live event where Grisham will speak. That event will be taped and become a podcast.

Those 200 also will be able to meet Grisham and have their books signed, he said. The deadline for the drawing will be May 19 so out-of-towners can make any travel plans they need to.

Even if people fail to win the drawing, they still can get a signed book from Grisham, he said.

Howorth praised the new book.

“I love the literary references and antics,” he said. “I think all of his fans, and maybe nontraditional fans, are going to enjoy this book.”

Camino Island begins with thieves stealing five handwritten F. Scott Fitzgerald manuscripts from Princeton University’s Firestone Library and selling them on the rare-books black market.
