Adi is a main character in the "Next Rest Stop: Earth" universe. She is an alien working on Earth and the one who introduces the lead character to the world within the Bermuda Triangle. She is described as being exotic and deadly. She's Princess Leia and Lara Croft with a touch of Pam Grier. The squid rifle isn't found in the story, but Adi needed a kickass weapon , and the squid plays nicely with the theme of the book/script.
