Who am I?

After a fatal plane crash, Tia Blackwell cant remember who she is or where shes from.
At 16 waking up in a hospital is scary. And the only thing she can remember is song lyrics.
And being adopted by the person who wrote the song seems scary at first.
Her life takes a change and she goes from being afraid to having the time of her life.
But with all her previous family and friends believing she is dead, how will they react to finding out she is alive?
Or will they even find out?

I suck at descriptions but please give my book a chance.XD
