Twinmaker is great for kids who want pure science fiction. Reminiscent of the world-building in Uglies, people now use “d-mat” to transport themselves anywhere around the world. However, someone is sending out a message saying that, through the use of d-mat and a code written on a piece of paper, you can change things about yourself. The only problem is that many of those who use improvement end up dead. Clair’s best friend has used improvement and now time is counting down to her death. Clair must team up with an unlikely boy at her school to figure out what’s really going on. This book is fast-paced, descriptive, and exciting. We read it for book club and everyone really enjoyed it!
