At the age of 3 your Dad, THE ex astronaut, billionaire. Jeff Tracy, decided that he didn't want to look after a daughter as well as 5 sons and the worlds most elite rescue team......so he put you up for adoption. your name is Grace Serena Tracy, your twin is Alan Shepard Tracy (that is his middle name, don't like it? just deal with it). before your dad gave you away he gave you a necklace, it has a silver chain with a red rocket ship pendant with a 'G' engraved on the back, and you have spent most of your life trying to find a match :PAll Rights Reserved
