Remember when love was sweet and innocent? You do if you belong to the era of picking up your date at the doorstep, holding doors open and asking the permission of fathers to marry their daughters. Today the way we talk about love and relationships is a bit more complicated, a mixture of the old ways and the new. These eight books will help you navigate that conversation, no matter what era you belong to.

Sarah Lotz dabbles in many genres. She has written urban horror, mysteries, short stories, screenplays and pulp-fiction zombie thrillers with several collaborators, including her daughter. Lotz has also admitted she has a fondness for fake names. But for her latest novel, The Three, Lotz is the sole author writing under her own name, and the result is a mind-blowing book with more than a few breathtaking twists that will keep you guessing all the way to the final page.
