Gr 9 Up-An engaging first book in a new trilogy by the author of the popular "Evernight" series (HarperCollins) that focuses on the possibility of multidimensional travel and its implications. The novel grabs readers from the first page: Marguerite Caine is hot on the trail of her father's suspected murderer. She and two graduate assistants are able to travel between dimensions using "Firebird" lockets that her scientist parents developedthe theory being that one can only jump into a dimension where a version of oneself already exists. Travel is risky, as there is always the possibility of becoming stuck away from one's "home" dimension (or worse). The various dimensions are interesting once readers suspend disbelief as to how quickly the characters are able to adapt to a new environment simply by applying a small amount of research. It's easy to be swept up in Marguerite's confusion over her romantic feelings for two of the characters and in the mystery as to who is truly behind the crimes against her family (for nothing is as it seems on the surface). As Marguerite unravels the truth and discovers more about herself with each leap, further questions arise: Is it ethical to hijack another bodyeven if it's an alternate version of yourself? Are there cycles of betrayal? Does fate really exist? Background information is weaved seamlessly in this well-blended mix of adventure, sci-fi, and romance that will appeal to a wide audience.— Sherry J.

It is not easy being the only artist in a family full of scientists. Marguerite is the daughter of the two scientists who developed the Firebirda device allowing the wearer to transmit their consciousness into other dimensions. When Marguerite's father is murdered and the prime suspect is his intern, Paul, Marguerite does not hesitate to chase him across as many dimensions as it takes to bring him to justice. Theo, her parents' second intern, helps Marguerite operate their stolen Firebirds and navigate four different dimensionsa futuristic London, a dimension with a still-intact Tsarist Russia, an underwater city, and a reality eerily close to her own. What Marguerite does not expect is how her complex feelings for Theo and Paul will magnify as she encounters different versions of the people she thought she and her family knew so wellor how deep the plot surrounding her parents' invention really goes.A Thousand Pieces of You is such a pleasant surprise. Where dystopia and love triangles were expected, there was a series opener that has its roots in old-fashioned science fiction, and the wings to carry that to modern teen readers. And it is not a love triangle when the main character knows what she wantsin several dimensions. Questions of fate, destiny, innovation, technology, war, and the ethics of consciousness add depth to an already intricate plot without weighing it down. There are some issues with pacing, including a slow start, but every moment in a modern Tsarist Russia makes up for it. This is a good pick for public and school libraries.Allison Hunter Hill.
