Wrapped Up In Books has a series on her blog called Like, Try, Why, where she recommends books based on other books readers liked.
I always enjoy seeing what she recommends, and have enjoyed discovering new books that I hadn't heard of before.
She is clearly very familiar with a wide range of YA books. Her job as a librarian probably helps with that.
I learned about her from a guest post she did on Stacked. (A site that probably deserves its own Feature Friday post.) You can read the guest post here, if you're interested in readers advisory, librarianship, book lists, or are just looking for something insightful to read.
If you're stuck and don't know what book to read next, I'd recommend checking out her infographics for help! They've certainly helped me before!
