An idealistic teen from rural Texas embarks on the adventure of a lifetime when she decides to leave behind starry nights for big city lights. Thrilled to be on her own and determined not to be intimidated by New York City, she accepts a job as nanny for a high-profile couple with four kids. Helping to keep her moral compass in check are Bertram, the family's butler, and Tony, the building's 20-year-old doorman.

Cody and Zack are approached to join the Gemini Project, a high-tech research center studying the dynamics between twins. Shockingly, they find themselves interconnected in a whole new way! When one twin experiences something, the other twin feels it too. This newfound revelation helps them see eye to eye for the first time, and it puts them in more danger than they could have imagined.

Zack and Cody Martin are aboard the SS Tipton, a luxury passenger cruise liner owned by London's father. The ship cruises the world with tourists and students who attend classes at Seven Seas High, the one high school that London's dad thinks will make his daughter a better student. While out at sea, Zack and Cody still have their compass pointed towards mischief, and London learns to live a "fabu-less" lifestyle, including sharing a small room with Bailey, a country girl from Kansas.
