A Mafia Boss Got Me: Nico - Just Bae's Dark Mafia Romance Collection, #5

They call me Phantom in the Bureau-a lethal ghost drifting through Chicago's criminal underbelly, an undercover threat looming in the shadows. To take down ruthless mob boss Dmitry, I sacrificed my humanity long ago. Until Jessica blazed into my life, a tantalizing temptation I can't afford but can't resist. She was supposed to be a means to an end, a pawn to destroy the Pakhan. But the irresistible fire in her eyes stirred a forbidden craving in me, one I hadn't felt in forever.
I tried to cast her from my mind, to let her retain her purity untainted by the grisly world I inhabit. But when she's snatched from my grasp, all restraints shatter. I'll defy every command, cross any line, to keep what's mine safe from harm. The Bureau can hang me when this is over, because I'm going to unleash a phantom's wrath unlike anything the underworld has ever seen.
