I was not sure what I expected. I did enjoy this book. The first half was confusing to me. I had a difficult time staying with it. However, I stayed with it. And I was glad that I did. This is a story about time travel and universe hopping. There are clones, aliens, and humans. The hero, Angus, and the heroine, Erin, are matchmakers in their time period, 1958, on Earth. They are taken from that time period and that Earth and placed in 2497 on a very different Earth. The male matchmaker was fun and interesting. The hero and heroine also have a Scottish accent. The writer maintains this accent all through the book. The matchmaking is done between the Earth women and the alien males. This service is not wanted but necessary. The aliens need the females to help repopulate their home worlds. The people on Earth need the protection of the aliens. The aliens take on human characteristics. They show emotion by tone of voice, extent of vocabulary, and gestures. By the end of the book, I wanted to see what happened next. I will probably reread this book as it does engage you. I will also read the next one in the series.
