Bumblebee can hardly remember a time without his foster sister, Firestar, in his life. He and his father took her in when he was only 10 and she was 8, so they've been like siblings for the majority of their lives. However, unlike Bumblebee, Firestar's birth-parents are still alive, and for the past 7 years have been fighting for custody over her while she's been in foster care.
Lately the case had been going in circles, neither parent really working that hard to win back the rights to their daughter, but suddenly her father starts taking much more serious steps toward custody, and the small foster family is forced to consider the possibility that they may not be together for much longer.
Will Firestar's father win her back, finally ending the awful conflict in their family? And if so, how will Bumblebee cope with losing the girl he has come to love as so much more than just a foster sister?
A semi-ordinary teenage girl who has had to fend for herself for many years due to emotional neglect from her parents, taking part in an underground adrenaline rush just to find a sense of herself, finds herself with a yellow camaro that her dad graciously agreed to help pay for. A camaro with a secret and a war brewing from the stars arriving to the planet. A war that was not her own, but she will come to learn as part of her family's legacy.
Facing the dangers that come with the beings from the stars, the leading commander of the autobots finds himself looking at this young human in a way he has not looked at another for a very long time. Her fiery nature is a shield, one he could see through upon their first meeting. One he learns she has built around herself to protect herself from pain.
As for the girl...there is more to this autobot leader than meets the eye. She slowly finds herself a new family to surround her with affection she has never had in her life. It is alien to her, just as alien as the autobots themselves. However...that is just what interests her. Especially Optimus Prime.
