This book--AARRGGGGHHHHHH! Not my idea of a love story. With all the jumping from time era to time era I think I got lost in time. I found myself having to go back to the headings to remember everyone's ages at the time. This could well have been called just " The Time Traveler." I thought the plot centered more on Henry than it did on Claire. Also, I had a tough time grasping the idea of going back in time and interacting with yourself. Wouldn't it cause all kinds of paradoxes? The author has Henry saying he can't take anything through timr for fear of altering the future.{ paraphrasing } But at different points in the story Henry goes back in time and teaches himself how to pick pockets, gives advice to his friend on the stockmarket, and when he has a vasectomy at age thirty-seven goes back when he's thirtyt-three and gets Clair pregnant. Wouldn't those things alter the future? Interesting premise but not my cup of tea. Larry
