Author Claire Seeber discusses her new book, The Birthday Reunion. Claire is the author of nine books, all of them dark, twisty, psychological thrillers. The Birthday Reunion is no exception. This novel is a twist on the domestic thriller, featuring four middle-aged women who were best friends in their early twenties but haven’t spoken in twenty years. When three of them are invited to the fourth woman’s birthday party on a gorgeous island in the Mediterranean, the four women reunite. And in typical Claire Seeber fashion, everything goes horribly wrong.
