Pain Without Love

"It's not a hook up and it's not drugs, although I promise you it's way more addictive than any drug you will ever try.
I'm offering you a way to end today feeling as though you really had spent time at Disneyland, like all your Christmases had come at once, like you had won the lottery, like you had died and gone to the most beautiful heaven... Imagine all of those feelings rolled in to one. That's what I'm offering you Shaw, now do we drink up and leave or do you spend the rest of the night wallowing in your own misery whilst everyone else gets on with their life around you?
The choice is yours, but I only make this offer once"

Fresh from a brutal breakup Shaw Peters meets mysterious 'Lena' in a night club, heading back to her apartment after one too many tequila shots he's surprised to find a casual hookup is not what's on offer.
Instead, after stripping down he finds himself being introduced to a world he could never have imagined, a world that goes against everything he was ever raised to believe about being a gentleman and a world that has him questioning everything he thought he knew about himself.
Who is the mysterious Lena?
And what can she teach him about Pain Without Love?
