At 39, Jennifer Weiner may be a bit gray in the roots to be writing about BFFs, but her previous hits like Good in Bed and In Her Shoes get her latest title a slot on our list. What's the story? Childhood best friends, one is popular and the other an outcast, and then they grow up. The outcast succeeds, the popular girl fizzles. And one day, the Tina Fey protege turns up at Miss Peaked-Too-Early's door and says "Something horrible has happened, and you're the only one who can help."
But what's it really about? Everything a book that features two women walking carelessly, clouds overhead, on a sandy beach should be: living through tragedy, finding unexpected love, and being best friends. Forever. Out July 14.
