Recursion

What if you had memories of things that never happened. For example a husband and child you'd never had. This is what False Memory Syndrome (FMS) is. What if you found out that FMS is the result of time travel.
This book was really interesting. I kept rooting for Helena. It was realistic in the fact that time travel had consequences. What if the time machine got into military hands or a group of people who want to use it for evil?
Good story and great main characters.I'd recommend it to my friends.
