Just finished reading it: it's quite enjoyable, thought provoking and has an open ending rather than a "happily ever after". Quite briskly written, as you would expect from a journalist, the plot's well structured although the how and why someone might go on the game is a bit predictable. To be fair, the book is as much about the main character searching for an escape from the demands of her conventional life, as about her sister's time as an escort. The blurb describes the book as sensual but the sex parts are quite perfunctory … which is probably deliberate, the author trying to make the point that the sex is brusque and mechanical …
Laura Lee gets a namecheck in the acknowledgements, along with a couple of escorts who shall remain nameless, M and N.
