Monsters, serial killers, and imaginary friends—being a Wonderlander can be murder...

Once upon a time, Kayla was lost. Then she found Wonderland, but not the one you know. Run by ex-government agents and funded by an eccentric Silicon Valley billionaire, this Wonderland is the name of a collective of highly trained vigilantes who hunt serial killers. Now Kayla, aka Mouse, works tirelessly alongside her fellow Wonderlanders, Rabbit and Cheshire, baiting dangerous murderers. But even her extensive training hasn't prepared her for the return of her older brother...

Shilo has spent most of his life in an insane asylum, convinced his mother was abducted by a sinister Alaskan monster who lures the lost away to feast upon their flesh. And now he's certain that his sister is in the same monster's crosshairs. But if Shilo is going to save what's left of his family, he'll have to convince his sister that maybe, just maybe, we're all a little mad.
