Book of Mara - Into the Void: Book of Mara, #1

Book of Mara is an explicit portal fantasy series about a woman whose life changes the moment a mysterious tome passes through her hands. What should have been an ordinary day at work quickly spirals into something she can't explain, or control. Now she's stranded in an unfamiliar world, bound to the very being who brought her there. If she ever hopes to make it home, she has no choice but to surrender to every dark fantasy she's ever had.

Part one of an ongoing series. Each book brings Mara face to face with a new creature or corner of the world, while a larger story quietly unfolds in the background.
