Lil has come to terms with her life as a Guardian/demon hunter and the wielder of the Nephilim most powerful weapon. But trouble looms in the Guardian enclave. Bran is pulling away from her and her best human friend is in trouble, and it's all Lil's fault

Bran and Lil may have escaped an attempt to lure Lil to the dark side, and recovered the contracts damned people signed with Bran when he was a soul collector, but someone forgot to tell them that no one switches sides or cancels contracts without consequences. Hunted by an unknown but powerful enemy, Lil, Bran and the Guardians must seek help from unlikely sources to avert total annihilation of the Guardians. When they finally face their enemy, one of them may have to make the ultimate sacrifice.

"Forgotten" takes the Guardian Legacy series in a new direction, as Lil wakes up on Mount Hermon Island after months of unconsciousness only to find that she has no memory of her life before waking up. As she learns about life there, and deals with her father and half-sister, she learns about the rules of society among the Hermonites and champions the cause of the minions, those who were unlucky enough to be born without powers. As she moves forward toward fulfilling her destiny as the one who will unite her people, she has to balance her responsibilities and her love for Bran.
