Dangerous Games by Nikki Rose

Hailey has three rules for her love life: Have fun, keep it simple, and don’t fall in love. These rules worked well until she’s brought face to face with the man who inspired them.
He broke her heart and let her walk away. She filled her nights with casual sex and one night stands, vowing to never let a man close enough to hurt her again. But when fate throws them back together, Hailey will learn that things aren’t always what they seem.
Struggling to look beyond the pain of her past to work with the man who broke her heart, Hailey risks losing it all when she finds herself in the middle of a very dangerous game.
