The Secret of Wings

Lily seems like the average high school student to any outside but inside she hides secrets.
She and her brothers are the first of their kind, half human and half bird, they were genetically engineered at birth for a government experiment. They are allowed to live in public is they follow a few seemingly easy rules:

1. They must keep silent about their past
2. No one can ever see their wings

For years Lily has worked to hide her wings from everyone at school and with the help of her brothers she has always succeeded, but could her newfound friendship with one boy jeopardize her whole future.
