Matt Fuller is an MIT research assistant in 2050 who accidently creates a time-machine that only goes in one direction--the future. And each trip is 12 times further in time than the previous, which thrusts him into some odd civilizations. One trip lands him in a society that has turned its back on technology and basically is ultra religious. It's here he meets a woman named Martha--and ends up taking her with him on his next trip, where people live a long time and have a seemingly life of leisure.
I found this to be a somewhat anachronistic time-travel novel. It feels as if it was written in the 40's or 50's, which may be the author's intention. Also, there's not a lot of emotional ties to the characters. It's all very breezy.
