Book excerpt: Lucy Alvarez, a recent Spirit School graduate, is presented with a unique opportunity. She's asked to become one of Archangel Azrael's "Helpers," a group of spirits who guide the recently deceased to the afterlife. Lucy is definitely no stranger to death. She lost her mom when she was twelve, and at age fifteen, she was diagnosed with cancer, a disease that ultimately claimed her life. She's an obvious choice to work with the Angel of Death. To become a Helper, Lucy undergoes training with Archangel Azrael himself. The Angel of Death is a handsome enigma, cold yet compassionate, and difficult to befriend. School For Spirits: Angel of Death is the fourth book in the Spirit School series.
