" A seventh grader with whom I'm working picked this as a required, but free, choice. I'm not sure exactly why he picked the fifth in the Five Ancestors series without having seen any of the others, but I also read 'Tiger,' the first. I'm a bit more linear, I guess. At any rate, I found the writing in 'Tiger' prosaic and featureless at first, and the story flat and plain. But the book began to grow on me. Besides the fact that they're about child kung fu warriors, the popularity of Stone's series is due to lots of action and fast pacing. And they hold another enticement: characters are not purely good, nor completely evil. In 'Tiger,' Ying, an elder 'brother' who has seemingly gone rogue, appears to clearly be a bad guy. But by 'Eagle,' we learn he's not. Stone reveals the reasons why his characters make good and bad choices, and leaves it for his readers to judge. That's sophisticated, and pretty cool, for books aimed at middle-schoolers. "
