Great book. What I loved most was how realistic the characters were. Hunter, the titular widower, does not treat his recently deceased wife Kait as if she were a monument to women everywhere. He makes no attempt to hide her faults, her insecurities. He openly rejects the idea that he should pretend she was perfect and that their lives together were perfect, but he doesn't need perfection. He loves her deeply anyway.
Their relationship had the same sense of realness about it - the stupid jokes they made over and over, the little games they played. Full of romance without sap, this was my favorite giveaway win so far.
