Stardust, by Matthew Vaughn

A young man named Tristan tries to win the heart of Victoria, the beautiful but cold object of his desire, by going on a quest to retrieve a fallen star. His journey takes him to a mysterious and forbidden land beyond the walls of his village. On his odyssey, Tristan finds the star, which has transformed into a striking girl named Yvaine. However, Tristan is not the only one seeking the star. Lord Stormhold's three living sons not to mention the ghosts of their four dead brothers all need the star as they vie for the throne. Tristan must also overcome the evil witch, Lamia, who needs the star to make her young again. As Tristan battles to survive these threats, encountering a pirate named Captain Shakespeare and a shady trader named Ferdy the Fence along the way, his quest changes. He must now win the heart of the star for himself as he discovers the meaning of true love.
