There is a time for everything under the heavens. A time to kill and a time to heal. A time to love and a time to hate. But when it's a time war you're looking at, it's Ryan Time. Jon is called back two billion years to save the Earth from an unprecedented threat. A alien clan is stealing time. It uses that time energy to power its quest to amass even more time. Soon, there will be no time for any race but them. No civilization has yet been able to even bloody the clan, let alone stop them. But that irresistable force is about to run smack into an immovable object, one pissed off Jon Ryan. As the very real possibility of never having existed closes in on humanity, Jon must rally his ragtag forces to do the impossible, yet again. But how can you defeat an enemy who can cause you to never have lived to face them in battle? A brilliant young scientist, Sachiko Jones, has foreseen the aliens' advance. Then she is thrust into a pivotal role in the defense of our planet. But though she commands unlimited power, she's a graduate student, not a warrior. If she can't learn quickly, the very worst outcome will be inevitable.Even a seasoned veteran like Jon is thrust out of his comfort zone. Time war is completely new to him, mind-blowing, and his enemy is a master of the skill. Battling -- surviving -- throughout all of time and space simultaneously defies common sense. One false move, one faulty assumption, and you're not dead. You will have never existed. And that which never was cannot be resurrected. It can't even be remembered. But, then again, impossible odds and cataclysmic consequences are what Jon does. It is possible, however, that just this once, Jon will find himself out of time.
