The Portal of Gods (Threshold of Gods Book 1)

Professor Steinbrook is undermined and humiliated by his colleagues and ignored by his students.
He and his assistant, Ellie, come across an archeological artifact with ancient engravings on it. The symbols are from several ancient civilizations from all around the world and from different eras.

Upon performing a ritual from a mysterious book, the Book of the Dead, they discover it is not merely an archeological object, but a portal to other worlds.

Steinbrook and Ellie quickly realize they are not freeing souls attached to objects but dealing with gods. They are, however, unaware of its dangers, the plan, and who is behind it.

Steinbrook’s and Ellie’s lives will never be the same.
