One Direction's Keeper

(my sister's keeper)
Most 16 year olds tend to think of 3 things:
1) the opposite sex
2) alcohol and parties
3) how they're going to try and not muck up their lives.
But not Rachel Smith. She didn't have time to worry about all those things because she was too busy learning how to cope with a brain tumour.
A brain tumour that only gave you a few months to live.
How do you begin to cope with that at 16?
I guess it would be a lot easier to handle with Louis Tomlinson from the world famous band One Direction as your boyfriend, right?
Not when he doesn't know and you have to keep it from not only him, but the rest of the world...
