Shadow Twins

In Iran, on a mission to rescue his mother-in-law, Paris Fox uncovers something he never could have expected, a mystery in the form of another almost identical twin. But this twin has a fantastic story to tell, one that may reveal the hidden seven-eights of Paris' genetic iceberg.
It seems his genes and those of his siblings have become a precious jewel that several Shadow Houses covet, chief among them the Borgias. They're determined to steal the biological treasure trove contained their bodies, and they'll go to any lengths to make that happen.
But does something more sinister hide in Paris' bloodline? Does he have an evil twin, one that intends harm to his Family?
The answers lie in the House of Borgia. To find out, he'll have to take them down hard. To succeed, he'll need all his skills and those of his siblings and allies. But if their combined might can't match the powerful Borgia Adepts, their lives are forfeit.
