Serendipity

In a dystopian near-future where debt can cost you your life, Ruby and Felix, two fiercely loyal adopted siblings, have become infamous for surviving the brutal, televised death matches known as The Circuit. Raised by a once-powerful businessman turned debtor, their adoptive father has used their victories to climb back from ruin-but at the cost of their blood and trauma.

Now entering their third and final match, the stakes have never been higher. Held in the frozen debts of Russia, this year's event promises carnage unlike any before-and the siblings' last chance at freedom. Their father has finally paid off the blood debt he owes... or so they think.

But when Orlov, a powerful and calculating Russian mob boss with deep ties to The Circuit, watches Ruby from the private viewing lounge, he decides she is the prize he wants most. And he will win with money, influence, and sadistic charm.
