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!

(Sequel to Truth to Uncover) Just when he thought he had the answers, Dipper's life was flipped upside down once more. His sister's been kidnapped, the rest of the demons from Weirdmageddon are human as well, and doubt has latched itself onto the young adult's mind. Trust is hard to come by in this world where danger lurks behind every corner. Is Bill really on Dipper's side? Or has this all been some elaborate scheme to get revenge? Can he really trust no one? Will he ever see Mabel again...? "No, not a deal. I'm done making deals... This time, it's a promise. One I intend to keep."

A/N: This book is a sequel to A Code to Decipher. If you found this book first, please go read the other one before reading this one. Thank you! ~*~*~*~*~*~*~*~ What do you look for if you don't know what you're trying to find? How will you ever get there? With nothing but a slip of paper to go off of, Dipper Pines is no closer to finding the dream demon he lost almost a year ago. Due to a spell the demon had cast upon him before he died, Dipper can't use any spells from the Journals until he is eighteen years old. With his eighteenth birthday on the horizon, Dipper is anxiously awaiting the day when he can use magic and find the one he has been looking for. Still though... Something feels off. If Bill Cipher really did come back to life, then... Why hadn't he come back to Dipper? Was something wrong? Was the demon in danger? Or had he never really loved Dipper to begin with? Had he only been using him? And who turned him human in the first place? There were too many questions with too few answers. As time goes on, Dipper grows uncertain... Was he looking for the demon? Or was he searching for the truth?
