Out Of Place Out Of Time

"Dr. Stowel made a big mistake: experimenting with unverified theories of time travel. The consequence was his sudden departure from Earth and his introduction to a sentient alien race. When he returns, many years later, he doesn't know how he got back, or why. Injured and suffering from severe memory loss, Stowel can only speculate that the aliens were responsible, that they are on Earth now and that they are up to no good. To the agents of the Temporal Exploration and Advancement project, Stowel's return could mean advancing their research by years. Yet with the risk of instigating an alien conflict as a result of their research, the project is at risk of being terminated instead! What is really gong on? Katherine Maya is certain there is more, locked inside the lost memories of Dr. Trenton Stowel. But how can she unlock the memories of a man who keeps disappearing into thin air?"--Amazon.com.
