I always thought that Nicc French was just another run of the mill writer you know, and I wasn't in a hurry to try her books.
Then when I was scrolling through Amazon I was reading up on one of 'her' books when I discovered that she was a they, naturally this piqued my curiousity and so I'd thought I'd try their books.
I've always liked reading books written by 2 people as it interests me to see if the books are well meshed together
Its not so much as a huge difference that she is a they, but it made me more curious to try, and when I'm curious I just have to find things out for myself, which is why I got one of her books!
