Can anyone please recommend a site where one can enter a book title and receive a specific age recommendation?
My reason for asking:
My daughter is young but has a high reading IQ, so finding books for her can be difficult. She's in 3rd grade, reading at middle school level (approx. 7th grade). There are some YA books I don't mind her reading but others I feel that are not appropriate. There are times, however, that I just can't tell. She borrowed my Kindle yesterday and there were only 2 books that I knew for sure would be both reading level and age appropriate.
There are many movie rating sites, but I have yet to find one for books. I'd love to see categories either as specific as ages: "8-10", "9-12" or a little more forgiving such as "children", "pre-teen", "teen", etc.
Suggestions much appreciated.

Thank you.
