A mute boy finds out about the Cybertronian race and befriends Soundwave, who was once also mute and deaf. Soundwave finds out the boy is Techno-Organic, and uses that to upgrade his body. The autobots "rescue" the boy, who is quickly changing due to his sire's faction, slightly torn between the two factions. But then their friendship is discovered...

19 year old Senna Smith gets more than she bargains for when she buys a autobot car by the name of Bumblebee. But when he transforms in front of her, she's surprisingly open to it. Becoming an asset to the autobots and a loyal friend to them, she's become one of the gang. A human autobot, who'd of thought? But when evils falls to Earth, she realises that blood doesn't make family.

Stay: Book One Tracy was normal. Human. No creepy special powers unless you counted her ability to turn situations around in her favor. But she won't be normal for long. She became special when she volunteered to give up her life as a human and become . . . an Autobot? One day leads to the rest of her life going from normal to extraordinary, and her bonds with the Autobots, one in particular, will be what gets her through the challenges thrown in her path, like when she is forced to face off with Megatron time and again. It's a deadly path she walks, and danger threatens her every move.

Tragedy brought them together. An accident means to separate them. Ironhide had never meant to let things go as far as they had, he had simply promised to watch over her. But fate and the Decepticons had other ideas.
