The monster under the bed is real. In fact, all the monsters are real, as well as the heroes and everything in between because all Fiction is real and exists in a dimension called Story. However, plenty of them hang out in the Mortal world, living both innocent and nefarious lives. This might not mean much to the average Mortal unaware of the Fictional characters living among them, but for The Last Scion--the only Mortal that can kill those Fictional characters--things are about to become very complicated. Tessa Battle is that Mortal. Upon her return to Lore, Oregon after years bouncing around boarding schools in Europe, Tessa had her sights set on simple things like shoe shopping, finding a hot boyfriend, and eating as many pancakes as humanly possible. However, the Last Scion mantle Tessa just got saddled with is not making any of that easy, and as Tessa and her new friends are about to learn, Story is long from done with her, no matter how much she'd like to deny her destiny. With more than one monster chasing her and questionable characters like The Snow Queen and Robin Hood as her allies, Tessa is going to need all the superpowers she inherited just to stay alive. And maybe, just maybe, it's a GOOD thing that behind her back, Stories call her THE STORYKILLER.
