I've just read A Tiny Bit Marvellous by Dawn French.
Dd really really really wants to read it. I suspect she's had a sneaky peak already and is attracted by the swearing. 
She has a very high reading level and I don't really censor her reading, but I'm not sure about this one. On one hand I think she'd get the humour, and I think the internet stranger danger would be a good message for her to have. But is it just a bit too adult? She is my pfb after all.
So, what do you think? Is it just to sweary? Would you let your 11 yr old read it?
