Hank Phillippi Ryan's latest novel, 'All This Could Be Yours,' is a thriller based on her own experiences as an author, she tells PEOPLE in an exclusive statement.

Emily Carroll's new adult horror graphic novel, A Guest in the House, seamlessly achieves that atmospheric element. The mechanics of its plot are a bit more unsteady.

The book has been a weekly best seller at BookHampton in East Hampton for the past month and a half. You can see its electric-green cover resting beside $200 Sunflow beach chairs.
