I am the real Clair Hill and I am telling you the truth.

We saved the world from Improvement but that was only the beginning.

The second enthralling book in the Twinmaker trilogy from New York Times bestselling author Sean Williams. Perfect for fans of GONE and Dr Who.

Clair and Jesse have barely been reunited when the earth is plunged into its biggest crisis since the Water Wars. The d-mat network is broken. People are trapped, injured, dying. It's the end of the world as Clair knows it - and it's partly her fault. 

"The girl who killed d-mat" is enlisted to track down the rogue AI known as Q, who is now missing. Q is the key to fixing the system, but she isn't responding to any calls for help, and anyway, can she be trusted?

Caught between pro and anti d-mat philosophies, on the brink of all-out war, Clair must decide where she stands - and who she stands with - at the end.

This is an edge of your seat story about technology, identity and friendship. Perfect for fans of Scott Westerfield's Uglies, and Ally Condie's Matched.
