From the back of the book:
In the dark corner of Vodacce lurks a criminal mastermind known as the Scarred man. Through strength, fear, and dark Sorte magic, he has carved out a comfortable empire for himself. But the threads of his destiny extend farther than he knows, leading to a pair of heroic innocents who hold the key to his demise. Helena and Ramon, lovers, fugitives, and Castillian patriots, have deep ties to the scoundrel's past. Unless your Heroes can help them, he'll see to it that they have no future. From the fields of Castille to the alleyways of Porto Spatia, the tangled threads lead into the heart of true love, thwarted ambition, and a most disagreeable foe.
