It's no surprise to anyone that Jeffrey Sachs, billionaire CEO of his own hotel chain, has a drop-dead gorgeous Estonian mistress. But stepping down to spend his retirement years with her? No one saw that coming - least of all his wife!

So now the prize of becoming Sachs CEO is up for grabs - and Jeffrey's four children have until the day of his wedding to compete for the job.

The front runner is Conway, the older son and golden boy. But Charlotte, a glamorous social media star with an Instagram-perfect family, is hugely ambitious, fully prepared to scheme and backstab to get to the top. Then there's the dark horse: Bella, her mild-mannered, hard-working twin sister. Or could Bart, the youngest child, a sexy, incorrigible playboy, somehow catapult himself into Daddy's good books?

In a game where the ultimate prize is power beyond your wildest dreams, you should never underestimate your competitors, even if they are family . . . and, it turns out, twins can be the most dangerous rivals of all . . .
