The Irredeemable Soul (Accursed Archangels #3‪)‬

Returning from the depths of the labyrinth realm, Thalia must come to terms with abandoning her quest to enter Heaven. When a malevolent stranger shows up demanding her cache of evil souls, she adamantly refuses.

As an incentive, the ancient and condemned Archangel Pelael takes her powers until she agrees to do as he asks. Frail and once again human, Thalia has no choice but to release one of the souls he desperately wants. Fighting to untangle herself from Pelael’s tenacious manipulations put her face to face with an old enemy who’s treachery knows no boundaries and threatens all she holds dear.

Fighting for a destiny far greater than salvation, Thalia must open her heart to survive an inevitable, all-consuming darkness.
