Transformers: Dark of the Moon Movie Prequel

Bring your young readers background on the Autobots and Decepticons waging their battle in the Dark of the Moon. First in Foundation, Optimus Prime crosses Cybertron with one goal in mind: to kill Megatron. But what led to this? Once, they were close friends--brothers under the mentorship of Sentinel Prime, aiding him in unifying Cybertron with the life-giving AllSpark and restoring the world to glory. But as the new sun set for the first time, Sentinel Prime told Optimus a secret... and that secret would change everything. Then in Rising Storm, Shockwave, the deadliest of all Decepticons, has arrived on Earth--leaving a trail of carnage behind him. Working under the command of the Depticon leader Megatron, Shockwave violently persuades the rogue Starscream to send his forces after the human Sam Witwicky and his Autobot friend Bumblebee. Autobot leader Optimus Prime responds to Sam's distress call, but this battle may cost the Autobots more than they bargained for. Prepare to witness the truth about the most bitter rivalry in the galaxy!
