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!)

After the Dipper Pines' and Bill Cipher's wedding, Dipper and Bill have been blessed with a beautiful demon human daughter named Diana Belle Pines-Cipher. She is the light of Bill and Dipper's life. But as the daughter of the greatest mystery hunter and the most powerful demon, Diana Belle wants to prove that she can be just as great as her parents! But will she be able to unlock mysteries that even Dipper, Mabel, or Bill couldn't figure out?
