Roxanne and the Blue Rose - Disney Fanfic

"The Rose will banish the Shadows forever and the worlds will be saved once again."

Roxanne lived her life struggling between life and death, due to her defective heart. The surgery on France would be maybe her last resort. But her family visit on Eurodisney also hides unexpected "guests".
Why is Peter Pan, Tinkerbell and Jack Sparrow together? And why through them Roxanne aquires the Blue Rose, a mystical necklace with amazing powers?
Together with them, and with the stolen pirate ship from Eurodisney, they embark on a journey to a world, where the fairytales are all true and the secrets of its Guardian lie within.
