I haven't read Lee Child, no. Am in two minds about him tbh (heard the stories are v good but the writing not so much), but might give him a try, thanks.
I love A Girl's Guide. But I read it years ago. That's just the sort of thing I'm after though. I liked The Wonder Spot by her too. I'm going to go onto Amazon and see whether she's written anything new recently that's in paperback <hopeful emoticon>
There is a short novel (or a long story??) by her, "The worst a suburban girl could imagine" (not 100% sure that's the exact title) which I think it's her best! She hasn't written anything else I believe.
