This is the third book in the Hearts of the Children series. I really liked the Children of the Promise series but was never able to get into the sequel series. However, I got interested a few months ago and began borrowing them from my sister. I've got to say, I find Gene to be a bit boring, but now that he's in Vietnam I'm assuming his character will get some more dimension. I kind of feel like Hans is thrown in so that we can know about the GDR, but I don't really feel vested in his story. I do, however, LOVE Kathy and Diane. I really like the way these young women are standing up for themselves and learning to be individuals but still maintaining their morals in a time when women were fighting for equal rights. This is a very good series, I may even like it better than the first one. This is in the books I own but haven't yet read category.
