Transformers Prime: the Orion Pax Saga

"When Unicron threatened Earth,Optimus Prime and Megatron joined forces to conquer the mighty destroyer. Though the enemy is defeated, all is not well in the Autobot ranks. Now, Optimus Prime is missing - leaving the Autobots without their leader. But that hasn't stopped the Decepticons and their dubious dealings. Jack,Raf and Miko will have to help their Cybertronian friends overcome great odds to find the great and noble Optimus Prime."--P. 4 of cover.
