The Time Traveler's Wife

I am now starting "The Time Traveler's Wife" by Audrey Niffenegger. Did you know that she is also a visual artist? This is a painting that she's done -- perhaps a self-portrait? She is a writer, artist, and professor in the Interdisciplinary Book Arts MFA Program at the Columbia College Chicago Center for Book and Paper Arts. I think it's fun that she is an artist of many media. From an interview with Mark Flanagan:

I teach writing to visual artists. We concentrate on merging and combining text and images, by means of artist's books, comics, installations, etc. I also teach letterpress printing, lithography, intaglio, fine edition book making, a seminar on visual narrative, and the occasional drawing class.

I really know nothing about this book, other than that a friend from work has threatened to bring it in for me for six months. I finally broke down and bought my own copy. I wonder if it will be difficult to keep track of the time jumps as I read. How will Ms. Niffenegger manage the changes? I've heard wonderful things about the book and I'm always a sucker for a good love story.
