Twenty-eight-year-old Mara Chen has built a billion-dollar venture capital empire through sheer determination and an uncanny ability to close impossible deals. She’s a total success professionally, even if her personal life is a complete failure.

Then a crazy, supernatural assassin with black eyes and gray skin breaks into her penthouse and wants to kill her for the cosmic power he says is inside of her. He nearly succeeds too, until a gorgeous stranger bursts in and slays the attacker in one lethal move.

He says his name is Caspian. He says he’s her immortal guardian. And he says if she doesn’t leave with him immediately, she’ll die.

Mara never dreamed she’d leave behind the life she’d built, but sometimes life decides for you.

Caspian is three-thousand-years old. He’s guarded forty-seven mortal hosts with Conquest, the first Seal of the apocalypse, encoded in their DNA. They live and they die. Always. Eventually. And he moves on. He’s perfected emotional distance, built walls that should be unbreachable.

When Mara becomes the new host, his instant obsession with her is concerning. The safest strategy is to keep his distance. But with her current location compromised, the only way to protect her is to move her to a remote Montana compound and give her a crash course in controlling her new powers.

Which means lots of together-time. Twenty-four-seven. A variable his defenses didn’t foresee.

Odds of them winning against an ancient enemy with a centuries-old plan? Terrible.  Falling in love? Absolutely not.
The math is awful. Everything’s at risk.

But the end of the world is just the beginning of what comes next…
