Query: A Little Bumpy but Still a Good Sequel

The series got a little bogged down in my opinion here, but the story is still good. My favorite characters still strive on despite drastic changes in their lives. Sam Yeager, the ex-ballplayer and sci-fi junkie, continues his role as guard of the Lizard prisoners. He even finds time to develop a relationship to Barbara Larssen.Liu Han and Bobby Fiore get transferred to a prison camp on Earth after she becomes pregnant. There they develop a relationship with Chinese Communists.Some old friends die, but then what would you expect, this is war. What Turtledove does with the remaining characters is enough to keep me interested in the outcome of the series.
