I read Nora Roberts' 'Time and Again' years back, and it has remained a favourite. It's about two brothers travelling from the future through a time warp, to our times. They discover everyday things in our life, like a bicycle or a stove, and I got to look at these from a critical, 'futuristic' light. The romance was sweet, with some angst.

I've been looking for more books like that ever since, but can't come across many. So I'd like to throw this open to my GR friends here. Any time travel romances where there are normal, regular H/h meeting across present and future? They could either move forward to the future, or could come from the future to the present. But no going back, please.

Thanks everybody in advance for any recommendations!
