I joined Shelfari when I first started this blog so I could get a bookshelf widget for my sidebar but only just discovered the book community there and all the different groups when I was searching for some newly released YA historical fiction books and found a new Shelfari Young Adult Historical Fiction group. I'm now a member and look forward to discussing YA hf including the books I review here and possibly (I hope!) maybe a guest review post.
If you like reading YA historical fiction, then I suggest you take a look at the group and some of the threads created there on this link . If you want to participate in discussions and become a member of the group, you will have to sign up for a Shelfari account.
