Reluctant Gods by A.J. Aaron

Past lives and past mistakes echo themselves for over five hundred years until an ancient agreement with the Archangels manifests itself to remind Leyna and Sevilen of their destiny. This is Leyna and Sevilen’s last chance to reunite and achieve the divine levels meant for them. Engulf yourself in this tale of romance, denial, disbelief, and shattering of paradigms among an outrageous cast of characters. Experience what it’s like to become a god in this blend of fantasy, comedy, mystery and romance.

This book is the first in this fantasy series about two pragmatic people. Sevilen, an engineering trained manufacturing executive and Leyna, a high powered executive are dumped into a world of magic where they gain abilities to create and destroy universes or, just throw a bolt of lightning or change into another body.
