Hello Jenn! Hope you like them heres their story: London and Nadia are step-sis/brothers. They were visiting their parents who were working for government (special scientists). This travel was horrible bc. they lost on the road. So they found this mystic island. They still dont know where is this place. They just wanted to see their family again. Thanks for reading! #usisland #usislandchallenge #jenn2606
