Nina Clay designs games for a living, but she never imagined she would become part of one. Successful computer game designer Nina works the world of fantasy, mapping out a journey through Hell as her next big game release. No one knows that this particular game is her way of avenging herself on the man who broke her heart, leaving her vulnerable to darker troubles. Into her life comes James Turner, a retired attorney in possession of a game unlike any Nina has seen before: an antique deck of cards that somehow hold the power to win anything, provided the player can afford the stakes and is willing to pay the costs. The cards even come with their own brutal enforcer, the otherworldly Magus, who wants nothing more than to see gamblers suffer the consequences of their bets. Nina is inducted into a new level of risk, able to win whatever she desires, whether it be a love affair for her lonely friend, a book thought lost to time, the perfect solution to summoning a particularly frightening Satan, or the inaccessible love of her life. Perhaps Nina is invited to play only as a fellow gamer. Perhaps her part in this game is outside her control. Despite being much older than Nina, James Turner is devilishly seductive, more than ready to take the place of the man who left her behind. Were relationships meant to be this easy, or is there something else at play? Nina suspects there is more going on, between her, James, and this deck of cards, than anyone has dared to tell her. The price of winning might be higher than she is able to pay.
