To be free. ----------------------------------- After two months on the run, Lucy finds a mysterious book hidden deep in the shelves of the Fairy Tail guild library. Curious she opens the book to find.... read to find out!? ------------------------------------ Sorry if the summary sucks. * I do not own Fairy tail, Hiro Meshia(?) does* Also NO LEMONS!?
