Hawaiian Honeymoon Homicide by J.T. Kunkel

What starts out as an unconventional honeymoon, with Miranda sharing the Hawaiian Island of Molokai with her new husband and relatives, soon turns into a murder investigation.

Several women from nearby cabins are missing, and Miranda can't help but feel for one young woman's parents, who've flown all the way from Ireland to search for their missing daughter. Despite some grumbling from the rest of the crew, Miranda enlists her family members to investigate.

After a local man joins the team, the sleuths have a pretty good idea of who the most likely suspects are. But can they get to the bottom of it all, or will it end up in the cold case file?
