Heaven High (The East Lake Series Book 1‪)‬

Beau had never given much thought to idea of dying let alone what might happen when he did. He was a confident eighteen year old and pretty convinced the grim reaper wasn’t out to get him soon. But when Beau and his best friend Edgar found themselves at Heaven’s door one summer night, he was quickly forced to accept two truths. There is most definitely life after death and you don’t necessarily escape what you’ve avoided on Earth...
They are faced with a stark choice and 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.
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.
