This is a question I'm often asked by book clubs and although I'm never NOT reading (my nightstand hosts a teetering tower of books) I do read many different genres. For example, I enjoy short stories and typically read 3-4 collections a year. Most recently these include Bobcat and Other Stories by Rebecca Lee, This Cake is for the Party by Sarah Selecky and Blueprints for Building Better Girls by Elissa Schappell.
Beyond that, I sometimes reread books that just won't leave me. I have a long list of these including The Help by Kathryn Stockett, Let the Great World Spin by Colum McCann, Water for Elephants by Sara Gruen, The Art of Racing in the Rain by Garth Stein, The Glass Castle by Jeannette Walls, Good Grief by Lolly Winston, The Fault in Our Stars by John Green... and on and on.
Last month, I read Caroline Leavitt's Pictures of You (a wonderful story/great book club pick), Liane Moriarty's The Hypnotist's Love Story (grabs you and will not let go), and Room by Emma Donoghue (a beautifully written, deeply upsetting and unputdownable novel).
