Steven Grant finds his very normal, very ordinary life in London upended when he wakes up with a voice in his head and a religious fanatic out to kill him ... unless it's all just a dream.
After losing his museum job Steven tracks down his alter ego, and meets the mysterious Layla, leading him deeper into the mystical world that Marc Spector is a part of – and face-to-face with the man chasing the scarab.
As Ammit summons his followers to release her from her tomb, Khonshu sends Marc and Steven to a gathering of the avatars of the gods. Layla takes Marc to an old acquaintance in hopes of finding the location of Ammit's tomb.
Steven and Layla grow closer as they make their way inside a long-lost tomb, where they find new dangers and another confrontation with Arthur – and where Layla confronts the truth about what happened to her father.
Marc is thrown for a loop after he is shot and awakens inside a psychiatric ward, where Dr. Arthur Harrow claims that the life he thinks he has is a figment of his imagination ... and where a talking hippopotamus claims he and Steven are in fact in the afterlife.
When Harrow succeeds in resurrecting Ammit, Layla turns to Khonshu for help in stopping her from conquering the world. Marc gives up paradise for one more chance to save his brother and return to the mortal world.
