Girl, without you I'm lost (GXG)

Sarah is an adopted Child.Her Mother was killed by her father.She doesn't tell anybody about it, she doesn't talk about it, she likes it that way, only her adopted parents know about it. Her New Family means the world to her,she wouldn't let anything happen to them.There the PERFECT family.....or are they? what will happen when sarah fall's for the new girl next door?Will she go for her or hold back her feelings because her mother is homophobic
