The rare book dealers who delighted readers with the history of their bookselling days in "Old Books, Rare Friends" now offer the other side of their story -- an intimate look at the joys of a relationship that has lasted more than half a century. When their friendship and business partnership began in the 1940s, Leona Rostenberg and Madeleine Stern were pioneers in a man's world. Now approaching their nineties, the duo, who -- among their many discoveries -- unearthed Louisa May Alcott's pseudonymous blood-and-thunder stories, remains a vibrant institution in the rare book trade, even as the Internet changes their field -- and their community -- forever. After publishing "Old Books, Rare Friends," Rostenberg and Stern received a flood of fan mail asking about their personal lives, and they have responded with poignant honesty and the warmth for which they are famous, as they reflect on their lives and their remarkable partnership. "Bookends" recounts their fascinating histories: family backgrounds, business adventures, the men they did not marry, and their approach to the bittersweet trials of aging. More than just a dual memoir,
