I gave in and let dd read Hunger Games because pretty much all the rest of her class (yr 6) seemed to be reading them.
I've just bought her the Inkheart trilogy for Xmas, if your dd hasn't read them they are pretty long
. Other series she likes, though I suspect your dd will probably have read them as they are all pretty mainstream are:
Artemis fowl
Rangers Apprentice
Skulduggery Pleasant
Eragon
Chronicles of Ancient Darkness
Northern Lights
Slightly more obscure perhaps:
Fly by night & sequel Twilight Robbery by Frances Hardinge - I think these are fantastic books, the language is amazing, personally I think although aimed at children they are worth reading for any age :)
Not exactly contemporary but dd has loved after they were recommended to me on here:
Dragonsong trilogy by Anne McCaffrey
Also:
Temeraire series by Naomi Novik (latter written for adults, I read the first 3 I think to check for suitability haven't checked out the later ones so can't vouch for them but dd did enjoy them)
The Last Dragonslayer by Jasper Fforde
DD wasn't particularly taken by the Terry Pratchett kids books, but they are very popular generally.
