When Brownsville attorney Alejandro Del Fuerte is asked to take over the prosecution of a case involving a Spanish land grant, he's excited about the potentially lucrative opportunity. There's billions in oil and gas royalties at stake. Not to mention the boost to his reputation as the "go-to" lawyer in South Texas for high-stakes litigation. But he needs to convince his partners in Del Fuerte, Fetzer & Montemayor to accept the case, and he knows his partner and fiance, Gigi Montemayor, will be against it. The defendant and owner of the disputed land is the Agnus Dei Foundation, which is headed by Bishop Salamanca, the priest she wants to marry them. And to make matters worse, the previous lawyers involved in the case have ended up dead or institutionalized.
