Mysterieuze schrijfster Victoria Spencer en haar dochter Darby Spencer worden als zussen aangezien terwijl ze raadselachtige zaken in Alder Bluffs aanpakken.

After a plane crash, two opposing half-brothers find themselves on an amazing lost island where enlightened pacifist humans and intelligent talking dinosaurs have created a utopian medieval society. But imminent disaster approaches.

Childhood best friends. Two halves of a whole. The cool, smart one who's good at almost everything, and his average, dorky friend who struggles to do anything right­—Yamato and Kakeru. Always by the other's side, but not together in the way they truly want to be. No matter how hard they try, their hearts cannot reach each other.
