Having saved the distant world of Caeles and its interstellar empire – not to mention the life of its ruler, Queen Dornoccia – Jim (aka Kid Sensation), returns to Earth with two notable prizes. The first is his long-missing grandmother, the alien princess Indigo. The other is Queen Dornoccia’s great-great-granddaughter, Myshtal, who is a princess in her own right and a budding superhero. And thanks to the machinations of the queen, she’s also Jim’s titular fiancée, a fact that puts something of a damper on Jim’s relationship with his girlfriend, Electra. It also doesn’t help that Myshtal is breathtakingly beautiful, personable, and witty – and lives under the same roof as Jim.
As if his life wasn’t complicated enough, Jim suddenly finds his world invaded by a doppelganger – an unknown individual who looks so much like him that he is even able to fool those in Jim’s inner circle. Even more disturbing, he also mimics Jim’s incredible slate of super powers.
Framed for crimes he didn’t commit, Jim is forced to seek out his lookalike in order to prove his innocence. However, as the depth of his double’s malevolent plans are revealed, Jim realizes that there is far more at stake than simply clearing his name. Now Jim faces the formidable task of attempting to stop an adversary who not only looks and thinks as he does, but also seems to match him power for power.
