Desiring the Dragon Lord - The Dragon Protectors, #1

How far will he go to save the only woman who can tame his inner beast? After witnessing the brutal murders of his family, dragon-shifter Logan Blake stumbles into the human realm injured and near death. His only goal is to heal and track down the fabled Blood Stone that can restore his dying realm. When a beautiful woman stops to render aid, he's unprepared for the instant bonding he feels to her.
Her presence fuels an unquenchable desire and he knows he has to claim her. Bree Anderson's morning jog is interrupted by the sudden appearance of a sexy, injured man in the middle of Central Park. When he turns up days later at the bar she manages as her father's new bodyguard, she knows he's going to be a handful. She also knows she's up for the job of uncovering who-and what-Logan is. But her determination to discover Logan's true identity is put on hold when a vampire mafia kills her father and turns their attention on her. Logan instantly becomes her fierce protector, until the evil of his past hunts him down in the form of the Drakana-dragon-hunters intent on killing him.
The only way he can save Bree from the vamps and the Drakana is to get her as far from the city as possible. But when both factions converge on their hidden location, Logan must make the ultimate sacrifice to save the only woman who can tame his inner beast.
