Airy Allies and Enemies — Anne R. Tan

A free honeymoon, an old ally, and a kidnapping. Raina Sun is enjoying her belated honeymoon with her husband, far away from her nosy family. When her grandma shows up to help a friend on a kidnapping case, it's bye-bye smooching time. Her husband gets volunteered to do the ransom drop, and an old ally from the Nine Dragons Triad, a multi-generational criminal organization, barges in for a visit. Things go from bad to worse when a body is found at the luau. Her husband is right. There's no such thing as a free honeymoon. Someone has to pay the piper one way or another. Will Raina find the devious killer, or will she become the next victim?
