Weirdmaggedon Two: Their Last Chance

After the last Weirdmaggedon, Bill Cipher, as he was about to die, invoked the power of the axolotl. His soul was preserved, but not in the way he expected - in the ring on the finger of Celia Cipher, his half-demon daughter.
Honey Lavender has lived in Gravity Falls for centuries. She's seen Weirdmaggedon come and go and would do anything to prevent it happening again. But when Celia, with fragments of her father's soul enclosed inside the ring, unknown to Celia herself, Honey knows something is wrong. How will she protect the ones she loves from the approaching darkness- even if one of them is the girl who serves as his gateway to Earth, Cipher's very daughter?
