From Booklist
Gr. 7-10. In late-twenty-fourth-century London, a secret government agency wants to destroy the Hex, young human mutants with supercomputer minds, but it hasn't reckoned on 15-year-old hacker Raven and her brother, Wraith, a former ganger, who are searching for their long-lost sister. With the help of a street kid named Kez and Ali, a spoiled teen whose Hex powers are just awakening, Raven and Wraith locate a highly secret facility that conducts unspeakable, illegal experiments on children who carry the Hex gene. The action is nonstop as Raven whizzes through the Net, setting up false identities and cracking top-secret security codes. The computer machinations and the sheer excitement of the occasionally brutal adventure will draw a lot of readers, even those who aren't necessarily computer savvy. It's a good start for this thriller noir series, which is imported from England.

Review
An elaborately conceived futuristic society is the setting for this thrilling trilogy. Brother and sister, Ravena and Wraith, are both Hexes, humans with a gene that enables them to communicate through machines and specifically the 'net'. The first book has them searching for their sister, who is suspected dead, but has been taken to a government laboratory to undergo horrific tests. In the second, Shadows, Raven joins with Hexes Ali and Revenge, to destroy the European Federation, that wants to destroy the Hex gene. The final part sees the introduction of two new Hexes, Gift and Talent, in Italy, who are in need of urgent help. All the threads come together in a literally explosive and satisfying conclusion.
