How I Magically Messed Up My Life in Four Freakin' Days

Ever wanted to grow a five-story tall flower in Central Park? How about fight a deadly battle under the subway tunnels of Manhattan?
Don't worry. I never wanted to either. But if you're ever being chased by ladies made of mist and have to save the girl with the sparkly eyes you've never had the guts to say actual words to, there's an app for that.
I found a magic cell phone, opened an app I shouldn't have, burned down my high school's theatre, and it was all downhill from there. A seer guarded by the undead is my only hope for keeping my mom alive, and I'm pretty sure the cops are after me for destroying my dad's penthouse.
But it gets better Now I'm stuck being the sidekick to the guy who got me into this mess in the first place. It'll be a miracle if I survive until Monday.
