Here is the beehive
(Book)

As an estate lawyer, an unfortunate part of Ana Kelly's day-to-day is phone calls from the next of kin informing her that one of her clients has died. Nothing could have prepared Ana for the call from Rebecca Taylor, explaining in a strangely calm tone that her husband Connor was killed in an accident. Ana had been having an affair with Connor for three years, keeping their love secret in hotel rooms, weekends away, and swiftly deleted text messages. Alone and undone, Ana seeks friendship with the one person who shares her pain: Rebecca. As Ana becomes closer to her lover's widow, she is forced to reconcile painful truths about the affair, and the fickleness of love and desire. -- adapted from jacket
