The Wonderously Strange Adventures of Farren Montgomery

Farren received a letter and some Scrabble tiles that spelled out 'Cayman Islands' one day shortly after graduating from high school. The letter told her simply to go, and didn't reveal who had sent it.

So despite her parents' protests, Farren goes, and she takes her three best friends with her. Through following the directions on that simple little letter, Farren has the adventure of a lifetime, finds herself, and unravels a complicated set of clues on the way to finding out who sent her that life-changing letter.
