The Earth’s in rough shape, and Lock may be just the maintenance man it needs.

A year ago, superpowered janitor and all-around geek, Loughlin “Lock” Ferguson somehow managed to save the world with the help of his oddball friends. Instead of a hero’s welcome, Lock had to flee from the government in order to protect the alien presence trapped in his head.

Now Lock must stop running and put his merry band of misfits back together, because another extraterrestrial threat has emerged, one that has hidden in the shadows of humanity for years, slowly changing the Earth in order to claim it for their own.

To discover what this new enemy is up to, Lock must go undercover at a space defense facility, and for that to work, he has to once again wield the tools he swore he’d never touch again: a mop and bucket.
