Betrayal's Shadow (The Guardians of Eden, #1)

What would you do to save your people from extinction? What if your race held the key to mankind's future? One Guardian will risk hell to change the future. Descended from the race of Guardians, Turen's people have survived the last two hundred years, quarantined and isolated. Living in secrecy with no mates and no offspring, they fail to deliver on their ability to replenish and heal human souls through the birth of their Guardian children. Risking his life, Turen chooses capture at the hands of a comrade-turned-enemy to seek answers to change the future. Mia Bowman has no knowledge of the secret Guardian race. Yet, her uncontrollable, nocturnal summons to Turen's prison cell and her strong sense of justice leave her with little choice but to help him. She can heed his warning and stay clear of his people's problems or she can ferret out the lies and unravel an ancient tale of murder and deceit.
