I didn't get much reading done on vacation but a few months ago AndiF lent me a sack of Brit Lit. I intended to take it with me on vacation but actually ended up reading quite a few of the books before vacation time even arrived. I just never got around to writing about it in the rush to get all my work finished so I could get out of town.
Falling, by Debbie Moon, is the story of Jude, a woman living in some future version of London, who is a "Retracer". Through a freak of genetic code she is able to jump backwards in time to any point in her life and change things. "Rarely enough to change history, but sometimes enough to shift the details of a conversation, change the routine of a working day."
