I might have bought the first book as a nice gesture to a friend, but I wouldn't have kept on reading, and waited impatiently for the next book and the next. I haven't finished Finding Home (I have this job that cuts into my reading time), but I'll provide a partial report. As you may recall from Repeating History, in 1959 Chuck McManis was visiting Yellowstone, when an earthquake threw him back into the nineteenth century. Finding Home now turns to his father, James, who hastily drives to Yellowstone in an attempt to rescue his wayward son (from the earthquake; he doesn't know about time travel).
James McManis didn't seem like an especially sympathetic person in the first book, and in some ways, he still doesn't, but he genuinely cares for Chuck, even if he doesn't express his love very well. Things develop, he learns more, and he interacts with new people. That's all I can say for now, since I haven't finished the book.
