Classics for a reluctant teen?

[TwentyOneGuns]

DD14 is an avid reader but tends to go for pretty lightweight stuff, I don't really care as I'm just happy she's reading but her school report suggested she try to balance this with some more classics as she starts GCSE.

I'm not especially up on adult classics although I've read most children's, but I know many of them would put her off straight away due to the dated or complex language. Can anyone suggest something classic that's maybe a bit easier and might tempt her to read more of this kind of book?

North and South by Elizabeth Gaskell. It's very light reading- an intellectual Mills and Boon minus the sex!

I wouldn't recommend King Solomon's Mines or anything much by Rider Haggard until she's really cut her teeth on classical literature from that era. I recall finding them extremely hardgoing as a youth a couple of years post-Jane Eyre. I think I only read them because I had nothing else to read!

I, Claudius by Robert Graves
Testament of Youth by Vera Brittain
Wild Swans by Jung Chang
The Handmaid's Tale by Margaret Atwood
One Flew Over the Cuckoos Nest by Ken Kasey
Mara and Dann by Doris Lessing
Lady Chatterley's Lover by DH Lawrence
Wives and Daughters by Gaskell (North and South too)
Moll Flanders by Defoe (Journal of the Plague Year is good too)
Miss Pettigrew Lives for a Day by Winifred Watson
War of the Worlds by H.G Wells
brave New World by Huxley
Collected Ghost Stories by M R James
