'Till Time Runs Out

What To Look Forward To

Darcy was what you could call a normal teenage girl... But this 'normal' teenage girl has a big life changing secret. 
Perfect life she's got her group of friends. Not the most popular girl but she was known. Not the smartest kid, but smart. Not particularily happy, but who could be with as big of a secret as hers. Perfect Family. Younger sister, who is probably the best sister you could wish for. Super star dad stay at home mom. Perfect Boyfriend, insanely gorgeous, insanely loving, but unaware of this secret.
What could this secret be.
