Phantom Warriors 7: The Dark King (Phantom Warriors Alien Shifter Series)

Taylor Shelley has the worst taste in men. When her ex turns out to be a
mobster, she's offered a chance to start a new life on another planet,
which means no more bad boys. King Hades doesn't have time to babysit.
What starts as an obligation, ends in a game of seduction where the
players are evenly matched. There's only one rule to remember when
playing with the Dark King--the house ALWAYS wins.
