Cute but Deadly by Beatrix Hollow

The asylum has fallen, and the patients have been let loose…

Nemo and Baz are the most innocent mass murderers the world has ever seen, so we’re laying low after breaching containment. Great plan … except we aren’t very good at it. Plus, the big, bad group that made Verfallen Asylum? Yeah, they show up to kill us. They’re cleaning house and want the worst first.
Guess the honeymoon phase is over, and it’s time to do what we do best: mayhem and murder. But escaping our enemies isn’t our only concern. Baz starts changing.
He’s becoming something worse, something deadlier, and this time he might kill us all, even if it’s the last thing he wants.

Author Note: Cute but Deadly is book three in a four book series and ends in a cliffhanger.
