Dipper and Mabel, now seventeen years old, have decided to stay in Gravity Falls with Stan and Ford. Dipper is still the same, a big geek and a bookworm, and Mabel is still crazy and cooky as ever. But what happens when Bill Cipher returns, Mabel gets kidnapped by him, and Dipper takes her place? And when these two become closer, will they fall in love? Or will Gideon, who's now in love with Dipper, stop them? (P.S: I don't own the art or videos in the story! I just thought they'd be perfect for the each chapter!)

Book 1 in a 3 Book series... Dipper and Mabel Pines are back in Gravity Falls for another summer. They may be sixteen, but the thrill of the mystery is still there! For the past few weeks, Dipper has gotten little to no sleep. Ever since returning to the Mystery Shack, his dreams have been tormented by a certain dream demon... One day, a stranger arrives at the door of the Mystery Shack. Yellow and brown hair, a triangular eyepatch over one eye, a grin on his smug face, the stranger lets out a laugh. "Long time no see, Pine Tree!" Having somehow been trapped in human form, Bill Cipher makes a deal with Dipper... Bill drives Dipper to the brink of insanity with his violent humor and overall aggravating personality, but there's something there making it impossible for Dipper to deny him help, and it isn't just the deal they made... A/N: The style of Human Bill in this story is Life-Writer's style! So...yeah! Just so you know, and so I don't have to try and describe him!

When the search for the supernatural brings Dipper and the rest of the crew on the Mystery Hack face to face with a creature beyond their wildest imagination, things start to get complicated... More than what he seems, the siren casts the crew's lives into turmoil, and it seems he's only there to make things difficult for them... yet there's something else going on beneath the surface... Demons and siren songs, creatures in the shadows and dark deals from the past. Will Dipper be able to restore order to chaos? Or will he be lured into the cold, dark waters? Will the song doom them all? Or will the siren find a reason to change his tune...
