Twin sisters Zoë and Karli Valentine were on a plane bound for Windenburg where they were going to visit their parents, when their plane had an engine failure and crash landed in the middle of the ocean. The girls were able to gather a few pieces of the plane, building a life raft allowing them to float. Days later, they ended up on a mysterious island, but they soon realized that they weren't alone. Zoë is the older and wiser twin, and Karli is secritive and very mischevious. #usisland
