Inescapable Gravity by Reina Torres

They were in love when they were younger, before she was torn out of his life. Now, he has the opportunity to save her life as her bodyguard. He won’t lose her again.

Marius Goddard has worked hard to get where he is. Going from a small town boy to a decorated Marine and now a top-tier security operative working for the biggest stars and, when it calls for it, people at the top of the food chain of business and politics. The brighter stars seem to shine, the darker the danger surrounding them becomes.
When he’s called to New York City, he doesn’t know who he’ll be guarding, he just knows that they’re in danger. Someone wants them dead.
He won’t let that happen.
When he walks into the room to meet his new protectee, he finds himself face to face with the only woman he’s ever let into his hardened heart.
Heather Vincent is the name on her birth certificate, but she can count on one hand the people who know her real name. Since she was a teen, she’s been known as Nix.
Name a famous stage anywhere in the world and she’s performed there and brought down the house. Suddenly, instead of standing in the spotlight, she’s hiding from it. A spotlight only gives her stalker another chance to end her life.
Her team has hired a guard to keep her alive, and when she finally sets eyes on him, she finds herself thrown back in time.
This was the man who’d taken her heart years ago and walked away from her. How can she spend hours and hours in his presence and not fall into his arms if he shows the least amount of interest?
Then again, what’s wrong with having one last taste of pure passion if someone is determined to end her life?
Marcus is determined to keep Heather alive because he’s never felt more alive than in her presence. After he puts a stop to her stalker, he hopes that she’ll give him the second chance he needs to show her that he never should have walked away in the first place because loving Heather is as inescapable as gravity.
