3,5 starsLet’s get this over with : this book is not focusing on a central love story, so according to rules that the author is not following anyway, this is not a romance. What’s in there for you, then?Love interests and maybe more if affinity. Note the plural but don’t hiss, there is no cheating, technically.A decent, if not spectacular mystery that triggered memories of the Famous Five and a clan offering many potential suspects and accomplices.A closeted cop.The fleeting, teasing presence of a Special Agent. The overshadowing presence of a best friend. Kudos to the author for making me like a character who was already dead when the story began! The victim is much more than a mystery plot device and this was the pinch salt that added to the story’s delicious bittersweet flavour.Stefan, writing children books when the only kids he likes belong to the past, and preserving his bitter and precious memories of them forever. Stefan always, who is a stopped clock, who numbed his emotions when he fled to LA, who is a stubborn smartass, who fights funny and is kind of dysfunctional but still trusted when and by whom it counts the most.A great narrative, not as much interrupted as fed by a child book manuscript that won’t let itself being written.No traditional romance, no neatly tied up HEA either, but an open ending that makes sense. The rush to the finish line in giant steps or easy shortcomings was a bit dissatisfying, too many things happened off scene and were told resolved but the author made up for it with an amusingly endearing ending.I liked Son of a Gun very much and I cared. I cared that Stefan stubbornly followed the track leading to the murderer because Tommy O’Connor was a good man and someone killed him, dammit! I cared for the childhood brotherhood, for Stefan coming home to mourn and for his late-bloomer coming of age story. I liked Stefan’s muse playing difficult and how it came full circle. I smiled and chuckled, too.There will be a sequel, right?
