Not Your Daughter Anymore

DNA test results: I'm not the Kelly family's real daughter.
Their actual daughter Sierra came home.
She got my room, my college fund, and my boyfriend started protecting her too.
The night our house caught fire, I almost died inside, but my boyfriend said "thank God the real family is safe."
"Figure out who you are first," he told me when we broke up.
My parents spent my college money on Sierra's clothes and suggested I take a gap year.
Fine. I'll figure out who I am.
Two and a half years later, I'm back driving a company car, scouting locations for a coffee shop chain.
Sierra's working three part-time jobs to pay bills, my ex-boyfriend's a temp worker at city hall.
My former parents are using coupons at the grocery store.
And me? I'm deciding whether to invest six figures in this town.
