This novella takes place between books 4 and 5.
Watching Damien’s two favorite siblings for the night—and stealing his sister Amelia’s title of “best babysitter”—should be easy. It shouldn’t involve his mom calling and begging him to watch his awful half brother. And it shouldn’t involve having to go rescue his two best friends from a superhero mission gone wrong. And it definitely shouldn’t involve getting stranded in downtown Golden City with all the kids he’s supposed to be watching. Especially not when the night’s almost over, and it’s a race against the clock if he wants to get everyone home before his parents and, more importantly, Amelia find out anything ever went wrong.
