Grojband in Gravity Falls

When Laney get's a call from her cousin Wendy, she and the band gets an all expense paid visit to Gravity Falls! While Corey plans a gig at the Mystery Shack, and Mabel gawks over the frontman (much to Laney's annoyance) Dipper realizes the band's arrival has triggered something in the town. Something ancient and deadly and secret. Two worlds collide in this new book, and if you don't know either of the shows I'm talking about, then you have no business reading this. I also don't own either show. I'm just a fan, keeping it real. Now, WHO'S READY TO ROCK!?
