No one else can stop them...

I've never loved Tristan more. I've never trusted him less.

Is it murder in his eyes or just jealousy when he insists we'll find answers in Boston, headquarters of one of our greatest enemies and home to the man I left back in Rio?

I haven't forgotten Kolt's betrayal nor the blood that's already been spilled between our families.

Inviting him back into my life with the promise of settling our unfinished business is a dangerous gamble that could end in more bloodshed.

But as his family's twisted plan starts to unfold, nothing can prepare me for the horror of what will happen if I do nothing. More people will die, and every death will serve a dark purpose.

Tristan and I may be an army of two, but one thing is certain—if we can't save them, no one will.
