Guilt can be a powerful motivator, but in some cases, guilt compounded by compassion, can lead someone to take action. In this book, the third in the Ape Quartet, sixteen-year-old John comes face to face with his own culpability for the fate of Raja, an orangutan who lived with the family in Georgia. John's father worked overseas, and when his ten-year-old son expressed interest in orangutans, he brought home one of the orphaned animals for him. Raja and John bond, of course, and live like brothers, but Raja grows larger as the days pass. When John's parents can no longer live together, his mother takes John and moves to Oregon, leaving Raja behind with his father. After his father loses his job and the house, he arranges for Raja to be moved to a West Virginia zoo with the ironic name of Friendlyland. Although John returns home to say goodbye to his friend, he ends up doing much more than that. Horrified by the conditions under which Raja has been living--almost forgotten and locked in a smelly trailer--he has second thoughts about where his friend is being taken, and heads to the zoo. After Raja and John make a daring escape, they spend days on the run, hiding in a motel and driving along the highway, until Dr. Jackson, the veterinarian at the zoo, helps him make arrangements to do the right thing and return Raja to Indonesia. John's supportive mother and Dr. Jackson pull strings, make the right contacts, and Raja, John, and his mother fly overseas. But even when they arrive, John comes to learn that things won't be easy for Raja, and he must make a choice between having his friend live in a sanctuary for the rest of his life or be placed in the jungle where he may face an uncertain future. Clearly, as readers will realize, nothing about this situation is easy, and the more they read, the more uncomfortable they may start to feel about their own actions or the impulsive actions that led to Raja's being brought home to John. The descriptions of fields being burned to make room for palm oil plantations and those of the animals that have suffered from human cruelty, selfishness, and neglect will tear at readers' hearts. And yet, as one of the characters reminds John, it's easy to blame the citizens of these countries for destroying the habitat while forgetting that those of us who live in the United States did the very same thing to the lands we cultivated. Because of the complexity of the issues raised here, readers will be touched on many different levels. There is no doubt that many of them will look for ways to take action, and the author provides some possible ways to do so. Fans of Endangered, Threatened, and The One and Only Ivan are sure to be moved by this book. Through the eyes of a naïve but compassionate teen boy with a conscience and a need to atone for his own mistakes, readers will be thrust into an emotional rollercoaster ride while wondering what they might have done had they been in John's shoes or those of his mother. The book broke my heart in many ways, but it also contained passages that made me smile and those that made me wince in guilt. As I read, I found myself wondering why it is that so many of us are touched by animals that seem more humanlike than others and why the very fact that a creature is able to feel emotions isn't enough for us to acknowledge that he/she is worth saving. Even our reliance on fast food venues and the consumption of animals as part of our diet are called into question here, making this book rife with discussion possibilities. Even as Raja himself is rescued from his lonely plight, perhaps the book's readers are rescued from their own thoughtless daily actions--or if not that, they are compelled to reconsider them. I savored every word of this moving story.
