Dangerous Passion by Lisa Marie Rice

Drake.
A dangerous, ruthless man who rules a billion-dollar empire with an iron fist. A man impossible to best, with no vulnerabilities. But when he meets the beautiful, gifted artist Grace Larsen, he learns the cruelest lesson of all … that feelings kill faster than bullets.
Grace Larsen lives alone inside an ivory tower of art and beauty, needing no one and nothing, Then her path violently crosses Drake’s—and as danger and passion flare, her life as she knows it shatters.
Suddenly, she is Drake’s weak spot—and a target for his bloodthirsty foes.
Their passion could cost them their lives.
