Blood Stone

Carmen Ortiz didn't plan on becoming anyone's savior. Hired to pull off the impossible—stealing a 412-carat red diamond from a fortified Siberian mine—she's assembled the deadliest crew money can buy. The target belongs to Viktor Petrov, an oligarch who guards his empire with mercenaries and brutal winter itself. But deep beneath the permafrost, Carmen uncovers a secret that transforms a precision heist into a desperate fight for survival—not just hers, but for lives she never expected to find.
