Camino Island by John Grisham

Princeton University has had five priceless manuscripts stolen in a spectacular robbery.  The only evidence left at the scene is a drop of blood which soon leads to the arrest of one of the thieves and an accomplice. The rest of the criminals and the manuscripts are yet to be found. When an insurance company manages to turn up a lead in Camino Island they contact Mercer Mann, an author and teacher struggling to pay off large student loans. Mercer spent many summers in Camino Island with her grandmother and is hired to return there and go undercover and be paid well. Mercer fits into the island well and soon befriends the owner of a bookshop.  Where are the manuscripts and where are the thieves?  Though this novel is unbelievable at times it involves books, authors and the book industry which kept my interest!
