Sir Gideon, heaven's most reputable guardian angel, professor at the University of Heaven at Paradise, master of the flaming sword, flight instructor, renowned author on the subject of humanity, and decorated veteran of the Demon Wars, has just been assigned a new case. Corey Scott is the insightful boy with the unheard of ability to see and hear his guardian as he grows from childhood into adolescence. The two become close friends, and Gideon forgets about the rules, the system, and the technicalities of being a guardian angel that he has developed over centuries of guardian experience. However, when Corey turns to his guardian for a miracle cure, Gideon tries to explain to Corey that even an angel of the highest rank and reputation cannot interfere in human destiny. A moment of spiritual blindness and self-pity leads to a misguided choice and Corey succumbs to the lure of evil and becomes aware of the awesome power of human free will. Despite Corey's perceived fall from grace, which becomes an almost insurmountable spiritual barrier, his lesson at the throne of God is a lesson for all humanity; Divine grace forgives all human failings and is extravagant beyond imagination.
