The Emperor of Any Place

Evan's father dies at his desk amidst shelves filled with ships in bottles and a yellowed, leather bound book cradling his head. It's a memoir of a WWII Japanese soldier stranded on a heart shaped island he names Kokoro-Jima. It is inhabited with ghost children that quietly follow him around the island. It also holds cadaverous jikininki or hungry ghosts that feed on the memories of the dead.

But what does that have to do with Evan's father, or his gruff estranged grandfather who has flown down to help settle affairs. It's Lost with a YA bent.
