Anyone might risk everything when death is just a heartbeat away.

It’s 2019 in America, and doctors Maya Copeland and Zhong Jian stand at the cusp of a technological breakthrough—transplanting 3-D printed hearts into human patients. If they can make it work, they’ll save countless lives, including that of the man Maya loves. And Jian could possibly right past wrongs that have haunted him since his clandestine work for the government decades ago in his native China.

Maya’s and Jian’s medical miracle will also cut into the profits of the Red Market, the underground trade of human organs. For The Golden Mirror, the ruthless leader of the Triad criminal organization, the drive to assert dominance in the Red Market is more than financial, it’s personal. But there is a weak link in his organization: the Triad’s newest “sister,” Daiyu, whose painful past propels her to try to topple the Triad and bring The Golden Mirror to justice.

Two heart surgeons. A heart patient. A heartless kingpin trafficking in life itself. So many hearts yearning to be made whole. When lives hang in the balance, who will live, who will make history, and who will get revenge?
