What if there never was a Neverland? What if the child in Peter Pan's shadow was forced to grow up? What if the monster you fear most is the one you're becoming?

In the turquoise waters of Palawan, where limestone karsts rise like ancient teeth and sirens guard their treasures in the deep, Jack and Baby Boy are best friends, partners, and thieves; diving for fragments of fallen stars to keep their starving village alive.

They’ve been inseparable since the night the sirens killed their fathers and left them to survive alone. They’ve never said I love you, but everyone can see it in the way they’d die for each other without hesitation.

Then the sirens strike again. Baby Boy is dragged into the depths before Jack’s eyes. When he escapes, he’s no longer the same—he’s stolen the heart of a siren, and it burns inside his chest, corrupting him from within. Jack has weeks to save him. Maybe less... 

The only cure lies in the hands of a ghost captain defined by his deadly Hook—a hunter who walks on water and commands the dead. He’ll trade the pearl of immortality for one thing: every shard of stardust Jack has ever stolen.

But Hook is lying. The sirens are hunting. And someone Jack loves could die.

Some loves are worth becoming a monster for.

And some boys who grew up too soon might lose the only person who ever made them believe they could fly.
