This fourth installment in the series has Eli, Thea, and Clyne time-traveling to cure slow pox, a plague that's crippling their society in 2020, but which has roots in ancient Jerusalem. The text is heavily reliant on earlier events and characters, and will seem hollow and confusing to readers who aren't already very familiar with the previous books.

Gr 8 Up-In Exposure, Julie dreads going to school because of her classmate Dana's constant bullying. When her brother brings home a digital camera full of incriminating pictures of her tormentor, she devises a plan for revenge that may just send Dana over the edge. The story is told from Julie's point of view, so readers get the full effect of the bully's behavior. The author also makes the point that revenge may not be so sweet as Julie discovers that making her nemesis feel bad doesn't necessarily make her feel any better. Her friend Sammy is the voice of reason, casting doubt on her plan. In Stuffed, a documentary about the dangers of fast-food consumption prompts Ian and his friends to boycott the local branch of a national chain. When he uses the Internet to gain support for his crusade, the restaurant takes legal action and he is faced with a difficult decision. Ian is an interesting character who is not easily manipulated or afraid to speak his mind. He shows that one person can make a difference. Both novels are quick, engaging reads. Well written and thoughtful, they will be popular with reluctant readers.-Michele Capozzella, Chappaqua Public Library, NY Copyright 2006 Reed Business Information.
