An Alien, a Time Machine, and a Hero

Five years have passed since Skylar Holden saved the world. He's no longer a loser, and his life is now on track. His job is going well. He's respected. He makes plenty of money. He even has a girlfriend. He has everything he ever wished for. Unfortunately, he's learning what it's like to live a normal life and deal with the daily grind. He misses the excitement and challenge his previous life provided, but now he's too afraid to risk anything in fear of losing what he's achieved. Alfred, the extraterrestrial who helped Skylar save the world, just got fired from his job as The Intergalactic Corp's observer on Earth. He's been banished to live among the humans for the next two millennia without interfering in their development. This is a light sentence for an alien, but there's a problem. An asteroid is on a collision course for Earth, and it's large enough to wipe out all of humanity-along with Alfred. The asteroid will not reach Earth for ten years, but Alfred's going to have to find a way to save Earth if he wants to survive himself, and he's completely cut off from The Corp and their resources. He's got a plan, but he's going to need some help along with access to some of the advanced technology he's stashed on Earth-in Skylar's stomach.
