The Price of Honor by Anna T. Pope

Betrayal runs deep in the underworld.

When Matteo Moretti, second son to one of most powerful crime family, barely survives a brutal ambush, he’s forced into an uneasy alliance with the last person he ever wanted to trust; Aldo De Luca, the man capable of anything, even killing his own father.
With enemies closing in and no safe haven in sight, they must rely on each other to unravel a conspiracy that threatens to bring both their families to ruin.
As they fight their way through the Sicilian countryside, dodging assassins and uncovering a plot bigger than either of them imagined, old resentments ignite into violent clashes. But in the heat of battle, something shifts as buried tensions give way to something even more dangerous; attraction. A single moment of weakness leads to a night that neither of them can forget, complicating an already impossible situation.
With time running out and a deadly rival orchestrating a hostile takeover, Matteo and Aldo will have to decide: can they set aside their past and survive the war ahead? Or will their families’ blood-soaked history destroy them both?
