Barbara Flores, a designer and cookbook author, gives a humorous look at marriage in “Separated, Acting Badly: A Bi-Cultural Memoir,” which she says shows “how not to write a memoir.” When her husband left her for a younger woman, Flores geared up to save her 30-year marriage. Of course, everyone she knew, both friends and relatives, had different advice for her, including luring him back with homemade enchiladas, rosary petitions and even witchcraft. Flores will discuss her book at 4 p.m. Dec. 7 at Murder on the Beach Mystery Bookstore, 104 W. Atlantic Ave., Delray Beach, 561-279-7790, murderonthebeach.com.
