Midnight Breed Series New Generation Box Set (Midnight Breed, #13-#15)

#13- BOUND TO DARKNESS:  Daywalker Carys risks her heart - and her immortal life - when she falls for cage-fighting vampire Rune. When the bodies buried in his past rise up to threaten his present, Rune must choose between betraying Carys's trust or putting her in the crosshairs of a battle neither of them can hope to win on their own.

#14- DEFY THE DAWN:  Born of different worlds. Bound by a desire they cannot deny. Immortal warrior Zael meets his match in Brynne, the strong, mysterious Breed beauty who's never dared to risk opening her heart to anyone - least of all a handsome immortal from a world on the verge of war against hers. Thrust together in a fight against a diabolical enemy, Zael and Brynne embark on a mission that will ultimately force them to decide between duty to their people, and a passion that defies all bounds.

#15- CLAIMED IN SHADOWS:  Vampire warrior Aric must decide between duty and desire when he falls for beautiful Kaya, a fiery trainee who gives as good as she gets. When Kaya's past reaches out from the shadows to call her back, she must decide between protecting a dark alliance that could shatter her dreams of joining the team and a truth that could not only forfeit Aric's faith in her, but bring the enemy right to the Order's door.
