Query: Well crafted - unusual plot

This novel is written primarily in sexual terms - memories of infidelities, present maritial and extra-maritial sex, and sexual fantasties; if detours here and there to explore death - real and imagined. It explores the relationship between a couple on a cruise ship vacation following the marriage of their daughter - an only child. While that description may not make the book sound interesting, the book is excellent - it has a tightly written plot with unusual relationships between its characters and with surprising twists that provide the insights into the characters' personalities that hold the story together.However, if you've read nothing by Montero, I would suggest either of her other translated books - In the Palm of Darkness or The Messager - as more indicative of her style.
