Darcy St. James returns to Alaska to join a journalist friend undercover on the trail of a big story. But when Darcy arrives, she finds her friend has disappeared. Troubled by the cruise ship's vague explanation, Darcy uses her cover as a travel reporter to investigate further.

The last person Gage McKenna expects to see during his summer aboard a cruise ship leading adventure excursions is Darcy. And in typical Darcy fashion, she's digging up more trouble.

He'd love to just forget her--but something won't let him. And he can't help but worry about her as they are heading into more remote regions of Alaska and eventually into foreign waters. Something sinister is going on, and the deeper they push, the more Gage fears they've only discovered the tip of the iceberg.
