Stranded (Book Three: Alaskan Courage) by Dani Pettrey

When her friend vanishes from a cruise ship, reporter Darcy St. James isn’t satisfied with their explanation that she simply left her job of her own accord. Something isn’t lining up, and Darcy believes the only way to find the truth is to put herself in Abby’s position.
Within days, Darcy learns her friend wasn’t the only person to disappear mysteriously. Last summer, a woman vanished under almost identical circumstances.
Gage McKenna has taken a summer-long stint leading adventure excursions for the passengers of various cruise lines that dock for a few days of sightseeing. He’s surprised to find Darcy working aboard one of the ships, investigating a troubling report.
Something sinister is going on, and the deeper they dig, the more Gage fears they’ve only discovered the tip of the iceberg.

I LOVE this series that features the McKenna family and their friends.  The Alaskan location is wonderful and "refreshing" as not a lot stories feature the winter climate.    Darcy St. James and Gage McKenna are the featured/lead characters this time around.  Their story is pretty special.  I was totally engaged with their story.  All the characters are well developed and believable.  Story itself moved along at a good pace.  I can't wait for the next book in this great series!
