Jason Davey has literally run away to sea after the death of his makeup artist wife, finding work as a contract entertainer aboard a much-adored but soon-to-be-retired cruise ship, the Star Sapphire.
But when three people from his past come board as passengers, Jason's routine week-long trip to Alaska becomes anything but.
First, a frightening, middle-of-the-night fire shatters his fragile sense of security and sets the rest of the crew on edge.
Then SaylerGurl, an anonymous and delusional stalker from Jason's Twitterlife, begins sending him taunting and threatening messages from somewhere on board.
Jason's wife was once employed by Diana Wyndham, a beautiful, aging and eccentric actress. Now Diana's occupying one of the ship's luxury suites, and it soon becomes murderously clear to Jason that she has more on her mind than her favourite stuffed monkey.
And hard-drinking ex-rocker Rick Redding, in the stateroom beside Diana, may know more about Jason's secret pedigree than anyone suspects.
Guided by his "guardian angel" Jilly - who he only knows as a constructed personality on Twitter - Jason - along with everyone aboard his beloved ship - must survive a trial by fire and ice on the journey to Juneau, Skagway and Glacier Bay.
A detailed observer of life above and below decks, Jason narrates his - and the Sapphire's - story with drama, humour, and a touch of the supernatural. And with poignant and dangerous parallels to recent tragedies at sea, you'll rethink everything you thought you knew about a voyage to the glaciers.
