When a 60 kiloton nuclear explosion destroys the University of Central Florida, terrorism is the first suspect. But terorrist don't generally leave doorways to another world in their wake. Or, rather, a generator of doorways to multiple other worlds.<BR>With time of the essence, the Secretary of Defense scrounges up the nearest physicist with a high level security clearance. With doctorates in everything from nuclear physics to electrical engineering, William Weaver, PhD, is the egghead's egghead. On the other hand, with skills in everything from mountain biking to screaming electric guitar, he's also fast enough and tough enough to survive when the alien gates start disgorging "demons."<BR>As a snap decision, he appears to be the perfect choice, smart, tough and capable. Now if he could only patch things up with his girlfriend, get his boss off his back and get his cellphone bill paid. Oh, yeah, and figure out why the heck these gates keep opening. Okay, so sometimes he's got priority issues.<BR>As the gates spread and evil aliens spread with them, it is up to Weaver and SEAL Command Master Chief Miller to find a way to stop the proliferation and close the hostile gates. The problem being that the only way they can see to save the earth is to destroy it. Then there's not going to be any more girlfriends or bosses.
