Query: Romantic suspense done right!

Federal Judge Grace Silva's husband has given their son to a Mexican drug lord as collateral on some investments. When the money and the husband go missing, Grace is given 48 hours to produce them or her son dies. She calls the only person who can help, Joe Faroe, an agent of St. Kilda (like the FBI, but without rules and government), whom she had a relationship with 16 years prior.The plot is engaging and believable, the characters are well-developed and authentic, and the writing is exceptional. The romantic scenes are hot without being distracting from the plot or cringe-worthy. A first rate novel. Had a hard time putting it down.
