As Cory takes a well-earned rest and finally submits to proper weapons training, he and a couple of people from his household go on a hunting trip in the marshland between Barresh and the turquoise sea. A bad storm has come through recently and on a deserted beach, Cory finds something Earthly that doesn’t belong there: a message in a bottle, a piece of paper with HELP scratched on it with a sharp object. In Isla. Cory has a list of all humans in Barresh: it’s very short and no one is missing. A few days later, he receives a curious message through official channels, from a woman on Earth whose rich businessman husband went on a trip of a lifetime “in a place where you can surf with plesiosaurs in turquoise waves”. Cory knows the guy advertising the trip. He’s a shady character. He also knows where the “plesiosaurs” are. They’re not particularly friendly. Not to mention that the area is on the land of a viciously territorial Pengali tribe. As it turns out, those are the least of his worries. Will appeal to readers of C.J. Cherryh's science fiction, Lois McMaster Bujold's Miles series, Lindsay Buroker, Anne McCaffrey and Glynn Stewart
