Pacifica Northwest traveled to the sleepy town of Gravity Falls, Oregon, the summer after her sixteenth birthday to visit an uncle she had met once and a cousin she had never seen. She expected a summer of running around in the woods, bug bites, new friends, and just being a teenager. She did not expect a strange journal filled with secrets, an uncle that couldn't care less, twins that were out for blood, and a terrifying man pulling the strings behind it all. She was sure she would never forget this summer.
