I just finished this and it was good. I am now starting #2 in the series, Poacher's End.
Strange happenings are going on off of Alaska's coast. Older retired couples enjoying their golden years murdered in particularly heinous fashions, a cop is killed, and a Skipper Frank Mattituck gets caught up in the investigation (deputized by an Alaskan State Trooper) when Frank's good friend Jim turns up missing, but Jim's yacht that he uses to charter trips for clients is still being used. Frank and Todd (the state trooper) go on a chase, trying to catch the elusive killer, always 2 steps behind. "Skipper's Oath" has lots of suspense and action, and if you enjoy a page-turning whodunit, this one is for you.
I received a copy of the book in exchange for an honest review-- thank you!
