When Damian Wayne and Jon Kent stumble across a massive, robin's egg-blue... well, egg, their first instinct isn't to call Batman or Superman it's to keep it. Obviously. Totally convinced it's a rare endangered species (and totally not wanting anyone else to take credit for raising it), the boys smuggle it home and tell their parents it's for a school project. What's the worst that could happen? Except, the egg is warm. It pulses with energy. And weird things keep happening around it-shadows flicker, electronics glitch. What they don't know? The "egg" is actually a healing cocoon for Danny Fenton, a half-ghost teenager from another dimension. Badly injured in a fight, Danny reverted to his dormant state-hoping to recover in peace. Instead, he's about to be raised by two overprotective preteens with a penchant for chaos and a complete lack of self-preservation. As Danny slowly starts to hatch, secrets unravel, powers clash, and the Bat and Super families find themselves at the center of something far stranger-and more heartwarming-than they ever expected.
