In this book, Sunita gets an internship at a lab. She finds out later that the animals are being infected with diseases, killed, and dissected to learn about the diseases to create new medicines for animals. Sunita is torn about whether or not this is wrong and at the end decides it's OK. While her friend, Brenna, gives the other side(against the experiments), saying that it is cruel and that there must be another way, that does not give any real facts for the other side. In all the other Wild at Heart books that involved animal rights issues, the kids did research to find out about the issues, but they didn't in this one. If they had, they would probably have found out some facts that very few people are aware of-like that experiments on animals are highly innacurate, have caused many drugs later found to be dangerous to be put on the market, and that 90% of medical advancements were discovered through experiments that did not involve animals. While I loved most the Wild at Heart books, I did not like the way this book presented the issue of animal experimentation;it was very one-sided.
