The Best Friend that Change Everything

Hi my name is Lily Rose Prior. I have a twin sister and brother. Theirs names are Beatrice and Caleb. We are all sixteen, so this is the year we choose our own faction after the Aptitude Test. My best friend left me 2 years because of his test. I never knew where he went hopefully i get to see him again, because I had the biggest crush on him but I can date just anyone i want. At least i still know his name, its Tobias, his last name is left to the unknown. Now to my life story.
