I feel compelled to review this book in a public forum. Katheryn Lasky is an excellent writer, and YAs should read all of her other books. This book, however, is a mess. The author obviously understands and has strong feelings about the moral implications of cloning. She does not understand the science of genetics. The book is rife with misconceptions and the worst kind of pseudoscience. Good science fiction is grounded in science; it is an extrapolation from what we know today. The characters are flimsy and the plot is ludicrous. It falls into the all usual traps that SF novels by non SF readers do. The society of 3038 is exactly like society today. Her characters read the newspaper and watch television in the year 3038! Television and newspapers will change drastically by 2038...they will be unrecognizable by 3038.
