Playing for Keeps by Stevie Rios

When the cruise ship full of fun-loving women pulls away from shore, leaving her stranded, Becca Neal realizes that she has indeed 'missed the boat.' What Becca cannot imagine is that the greatest adventure of her life is about to unfold. As she steps into the lives of an extraordinary circle of lesbian and gay friends, she meets Lindsay West, a grad student from Bloomington, who is principal oboist for the Filarmonica de Caracas. And Rob Heron, the dear gay man who is her best friend. And Mercedes Luego, Lindsay's gorgeous lover, who yearns to explore the Amazon- and does.
