Here's the description from the back of the book:
A most untraditional love story, this is the celebrated tale of Henry DeTamble, a dashing, adventuresome librarian who involuntarily travels through time, and Clare Abshire, an artist whose life takes a natural sequential course. Henry and Clare's passionate affair endures across a sea of time and captures them in an impossibly romantic trap that tests the strength of fate and basks in the bonds of love.
Wow, just reading that as I typed made me feel a little bit ill. I actually disagree with the back of the book on several counts. I don't think the book is a romantic trap. I think what happens in the book is unfair and almost cruel. Henry gets to travel through time and Clare is always left waiting. Always.
Because of the rushed nature in which I read this, I might give it another chance at another time. Maybe. I've got an awful lot of books that I want to read though...
