Comparing-3 revised

There were two series of novels that I had read; one was Millennium Trilogy series, and the other was Watch series. While Watch series were fantasy works, Millennium Trilogy series was a story about venture and humanity actions. And the background of Watch series was happened in London, but the background of Millennium Trilogy series was happened in America. And the main characters' personallity of those two series were different from each other. Also, there were four books in Watch series, whereas Millennium Trilogy series had three. Though the two series were quite different, their stories were still very exciting and interesting.
