Five contestants have been chosen to compete for ten million dollars on the game show One Lucky Winner. The catch? None of them knows what (or who) to expect, and it will be live streamed all over the world. Completely secluded in an estate in Northern California, with strict instructions not to leave the property and zero contact with the outside world, the competitors start to feel a little too isolated.

Korede is bitter. How could she not be? Her sister, Ayoola, is many things: the favorite child, the beautiful one, possibly sociopathic. And now Ayoola’s third boyfriend in a row is dead. Korede’s practicality is the sisters’ saving grace. She knows the best solutions for cleaning blood, the trunk of her car is big enough for a body, and she keeps Ayoola from posting pictures of her dinner to Instagram when she should be mourning her “missing” boyfriend. Not that she gets any credit. Korede has long been in love with a kind, handsome doctor at the hospital where she works.

Ike Randolph has been out of jail for fifteen years, with not so much as a speeding ticket in all that time. But a Black man with cops at the door knows to be afraid. The last thing he expects to hear is that his son Isiah has been murdered, along with Isiah’s white husband, Derek. Ike had never fully accepted his son but is devastated by his loss. Derek’s father Buddy Lee was almost as ashamed of Derek for being gay as Derek was ashamed his father was a criminal. Buddy Lee still has contacts in the underworld, though, and he wants to know who killed his boy.

Meghan, Brecia, and Skye have just one thing in common. They were all murdered by the same man. He hunted them online, masquerading as an eligible bachelor. Then he played the perfect gentleman, a thick layer of charm and a thousand-watt smile hiding the fact that his first dates end in shallow graves. He’s gotten away with murder three times now.

Simon and Vicky couldn’t seem more normal: a wealthy Chicago couple, he a respected law professor, she an advocate for domestic violence victims. A stable, if unexciting marriage. But one thing’s for sure: absolutely nothing is what it seems. The pair are far from normal, and one of them just may be a killer. When the body of a beautiful socialite is found hanging in a mansion in a nearby suburb, Simon and Vicky’s secrets begin to unravel. A secret whirlwind affair. A twenty-million-dollar trust fund about to come due.
