My Alien Daddies

Humans,
They've been on their own for way too long until their keepers are back.
They ruined their planet, they are ruining each other, it's time for them to get back home.
Humans are taken back to the mother planet and being raised again, to grow up like their alien relatives.
Madelyn was born to a resistance, her life was pure hell until she was caught and put back for adoption.
What would happen when three daddies decide they want her to be theirs.
