Dust by Kara Swanson

The truth about Neverland is far more dangerous than a fairy tale. Claire Kenton believes the world is too dark for magic to be real—since her twin brother was stolen away as a child. Now Claire's desperate search points to London... and a boy who shouldn't exist. Peter Pan is having a beastly time getting back to Neverland. Grounded in London and hunted by his own Lost Boys, Peter searches for the last hope of restoring his crumbling island: a lass with magic in her veins. The girl who fears her own destiny is on a collision course with the boy who never wanted to grow up. The truth behind this fairy tale is about to unravel everything Claire thought she knew about Peter Pan—and herself.
