No Negotiations. Assassin's Core, #4

On the verge of getting back to her normal, a new problem walks into Alexi's life. One of her employees is attacked outside her club and ordered to give her a message. Not sure exactly what that means, Alexi finds herself embroiled in a battle of wills with a human trafficker who threatens her mate's life. With that, the jaguar sees red and pulls out all the stops. As she's doing all she can to keep her mate safe, Tatiana undergoes a change of her own, one that awakens the darkness inside her.
As Tatiana slowly becomes a witch willing to kill for her mate, the enemy pushes harder and Alexi learns they've both been pawns in another man's game. But all bets are off and there will be no negotiations. There can only be one.
