Dark Obsession by Ben G.

She was never supposed to be more than a passing distraction. A college girl with too much curiosity and a dangerous innocence that made her irresistible.
But when Alina Carter stumbles into a side of billionaire Damon Cross that no one is supposed to see, walking away is no longer an option.
Damon has spent years hiding his secrets behind wealth and power. By day, he's a ruthless businessman. By night, he controls a dangerous empire in the shadows. He doesn't love. He doesn't do attachments. But Alina? She's under his skin.
The deeper she falls for him, the darker his world becomes. His enemies are watching. His secrets are darker than she imagined. And the one thing she thought was love turns out to be something far more dangerous.
Because in Damon Cross's world, love doesn't save you.
It traps you.
