Twinmaker — Sean Williams

M.T. Anderson meets Cory Doctorow in this teen debut from #1 New York Times bestseller Sean Williams, who also coauthors the Troubletwisters series with Garth Nix.

When a coded note promises improvement -- the chance to change your body any way you want, making it stronger, taller, more beautiful -- Clair thinks it's too good to be true, but her best friend, Libby, falls into a deadly trap.

With the help of the school freak and a mysterious stranger, Clair races against the clock and around the world to save Libby, even as every step draws her deeper into a deadly world of cover-ups and conspiracies.

Action and danger fuel this near-future tale of technology, identity, and the lengths one girl will go to save her best friend.
