Beau and Edgar have been best friends from birth, but couldn't have had a more different start in life.
Having finished school for good they make plans for the summer of a lifetime but a tragic accident cuts their dreams short and lands them in Heaven facing a stark choice.
Do they want to stay in Heaven and train as spirit guides or reincarnate into a new life?
For Edgar the choice is clear: Having had a miserable existence once before he is in no hurry to try again, for Beau the magic of Heaven is no match for real life. But his heart overrides his head and Beau agrees to stay with Edgar. They begin their training at Heaven High and await their assignment.
When they are offered a secret undercover assignment to protect Emma Havering the boys snatch the opportunity to live as humans once again. With their colleague Gabe, Emma's Guardian Angel, they attend East Lake High but soon become suspicious about the nature of their assignment and who Emma really is. Their curiosity leads to repercussions that test the limits of friendship, loyalty and the very existence of East Lake.
For Beau and Edgar, keeping Emma safe might very well rip them apart.
Heaven meets High School.
