I just finished reading Dan Brown's new book, The Lost Symbol. It was fantastic, go read it. It's long book, but a fast read. Robert Langdon is called to Washington DC to help solve a mystery involving the ancient brotherhood of the Masons. It's full of twists and unexpected character shifts making it a captivating story.
The second book you should read is My Sister's Keeper by Jodi Picoult. A genetically engineered girl fights for medical rights to her body after years of obligatory medical donations (Stem cells, bone marrow etc.) to help save her sister who's dying of cancer. Another great book, with a twist you won't see coming at all (At least I didn't).
So if you're looking for something to read, check these out, I'm sure you'll like them.
