I was giving this a bit of thought this afternoon, and there were some more that she might well enjoy. Kathy Reichs, who writes the Temperance Brennan ‘Bones’ books has written a Young Adult book called Virus, which has Tempé’s niece, I believe, and Tempé peripherally.
She might well like William Gibson’s most recent trilogy, the ‘Hubertus Bigend’ series. (Quiet at the back, there!).
Difficult to categorise, they’re sort of noir-ish, set in a kind of present day, but slightly out of phase, where tech is recognisable but just a bit more developed, great female characters, and fashion and clothes feature, too, with viral marketing of heavyweight denim, and obsessive Japanese replicas of American iconic Korean war flying jackets.
Look for Pattern Regognition, Spook Country, Zero History.
