Harlan, a technician from an organization called Eternity, alters time's cause-and-effect relationships for the betterment of mankind. One day, Harlan falls for woman who will or is erased from time, which leads him to mold time for personal gain-- to keep his love and live together.

I have to admit that I had to really focus and take scrupulous mental notes to make sense of the time travel; safe to say probably one of the most complicated time travel stories I've read. If you are a fan of hard sci-fi, time travel, and paradoxes, you will enjoy this book.
