Dark Karma: Sword of Vengeance (Karma Series Book 2)

Banished by his enemy into a hellish alternate dimension, Luke Decker fights to understand why his world has suddenly changed, and why is he on trial for the murder of his beloved Nina? What he doesn’t know is she’s not dead. Nina watches him vanish into thin air and is completely bereft, struggling to find out how and why he disappeared. Using all of her psychic talents and traversing the astral realm, she frantically searches for him to no avail. She owns a secret item which holds the key to his salvation, but will she figure it out before he’s condemned to live the rest of his life in a realm of darkness?

This remarkable tale of vengeance, time travel, and dark magic is even more enjoyable if you read Tough Karma: A Race Against Time first.
