Title: Greek's Last Redemption (The Chatsfield)
Description: Warning: imho, reading the GR reviews will inhibit the angst and impact.
They contain HUGE plot spoilers, official blurb has no plot spoilers 

Official Blurb: 
Returning to the marriage bed.
Waiting outside her estranged husband's lavish office, ready to demand a divorce, Holly Tsoukatos can't remember ever being so scared. Not even when she told Theo the words that destroyed their union.  Seeing Holly again, Theo hates how much he still desires her. If she wants to talk, he'll choose the venue: The Chatsfield, Barcelona, where they spent their honeymoon! 
Being so close again is delicious torture. Holly might have fled their all-consuming chemistry once before, but this time, Theo won't let her run away so easily… 
Welcome to The Chatsfield, Barcelona!  

Such a different take on Revenge?  trope
 a very brief marriage,  now separated for 4 years. She comes seeking a divorce, which he opposes. All that sounds like a normal HP 
BUT, And here's a big but,
It's twisted.
Neither of them are very nice, certainly not likeable. 
Try to make it halfway through chapter 5 BEFORE reading the GR reader reviews 
That will make the book ever so impactful.  
Definitely recommend, 
but a one-time only read
