Shadow, Don't Make Me Upset (Shadow Saga Series #2)

Shadow the Hedgehog, the Ultimate Lifeform created by Professor Gerald Robotnik 50 years ago. He never thought he would ever wake up from his stasis, but thanks to Gerald's own grandson Dr. Eggman, that turns out to be the case. Shadow soon plays the old "genie in a bottle" trick on the power-hungry man, and a half-century delayed plot of revenge is set in motion. Between Eggman's aspirations of world conquest, master thief Rouge's continuous eye on the Ultimate Lifeform, and the blue hedgehog who bears a striking resemblance to him, Shadow has his hands full even when he's biding his time. Still, his anxieties have their way of creeping back to him, no matter how he tries to keep them at bay.
Why does Shadow want revenge so much? What's the deal with Rouge and her constant spying on him? And just who is the blue hedgehog who looks so similar to him?
