Past His Defenses — Andrew Grey

When a case reopens old wounds from the kidnapping of his younger sister, police officer Robert Fenner is told in no uncertain terms that he needs a break. And maybe his superiors are right. He books a flight to visit an old friend, who happens to be the one who got away, and hopes for the best. 
Electronic security consultant Dixie Halewood works from his home in Paris, where he lives with his adopted son, Henri. Dixie doesn't expect a message from an old flame asking for a place to stay, but he agrees. Their past is just that -- the past.

Things between them aren't as settled as they thought -- Henri, Paris, and proximity work their magic. The two men are drawn closer and old flames burst back to life, but Dixie's work brings a new threat to their safety and the budding family they missed out on the first time around.
