D.C.'s top-secret military operation, Operation: Middle of the Garden, is the exciting backdrop for these strong heroines and sexy heroes who must team up to save the country, and themselves, from the most unlikely of sources: the immortals who hold the secret of the Garden of Eden. Join these four couples as they discover paradise isn't quite as tempting as real love:

• Of Eternal Life: Dr. Abilene Miller is shocked when a dead man jerks back to life in her arms and infuriated when he kidnaps her. He thinks she's part of a conspiracy; she thinks he's insane. Only together can they find out the truth - and brave the risks they run in loving each other.
• Of the Knowledge of Good and Evil: When faced with prison or joining the undercover operation, convicted criminal Dahlia immediately chooses to become a test subject. Her partner, Jericho Edwards, knows better. He was the operation's first guinea pig, and he must find a way to save them both.
• Of Consuming Fire: A terrible accident places Grace Tucker at death's door, and Jayden, the cherubim who guards Eden, allows the unthinkable to take place. He lets his intended victims heal her with the fruit from the Tree of Eternal Life. Too bad Grace is the one woman on earth who can bring him down.
• Of Alliance and Rebellion: A loyal soldier of the Garden of Eden, Anahita is faced with a daunting mission: to slay the three imprisoned immortals who ate from the Tree of Eternal Life. But once she lays eyes on prisoner Max Wright, her spirit wars with the compulsion to both kill and protect him.
