Time and Again by Nora Roberts (2001)

Knew I had read this just a few pages in, and I had even checked my list, but must have read this before I started the blog, so I kept going. These are science fiction romances, where two brothers from another time and planet come to earth and find their soul mates in two sisters from today's world.

Time Was (1989)
Pilot Caleb Hornblower crashes on earth coming out of the 23rd century after skimming a black hole. He lands in rural Oregon, where he is found by Liberty Stone, an anthropologist raised by hippies who has moved to the old family homestead to get some writing done. They dance around each other for a while, she has never committed to anyone, he has never wanted to - plus he tries to keep it a secret that he is from another time for a while. The main disbelief I had about the story-line was that his language would still be similar enough that she wouldn't be immediately suspicious. And when he stays, I was wondering how he would establish an ID, without a birth certificate, SSN card, driver's licence and all that stuff that says who we are.

Times Change (1990)
Jacob Hornblower comes looking for his brother to take him home, after the brother sends the ship back with a message of what happened. Jacob has to figure out time travel first, but he manages. Once he arrives, he meets Liberty's wilder sister Sunny, who has not figured out what she wants to do with her life, though she is good at everything she tries. Of course they find each other. Another thing I liked in the story is that Liberty's and Sunny's parents supposedly become rich and famous into the future - one an artist, another a seller of teas. Maybe this was written when Celestial Seasonings became a big deal.
