Forsaken Souls
Book Four of the Callum Walker series
The critically acclaimed supernatural series now fully relaunched with new covers and content by J.M. Shaw
The book is available worldwide in print and digital formats
Driven south by their brethren in the Northern Kingdom, the Der’geron have bided their time for nearly two centuries, nursing hatred and plotting vengeance since their defeat in the great elven war. As a new conflict draws ever closer, Queen Jobella struggles to assert her authority over her northern domain—battling civil unrest, sabotage, and misinformation while attempting to mend fractured alliances.
Meanwhile, Callum and Jax set out on a perilous journey to repair the veil separating the magical realm from the human world. Unbeknownst to them, their path leads directly into the heart of danger, where they are captured by the Der’geron. Imprisoned in the hellish grotto beneath the subterranean city of Elfarian, Callum and Jax are forced to work or die at their enemy’s command.
However, danger turns to horror when Callum learns of the Der’geron King’s plans for the Northern Kingdom and the rest of the realm. What is to come will be a reckoning, not a war. It will be a battle for the ages, where both lives and souls are at stake, and death is not the worst outcome.
Imperilled by violence, assailed by evil energy, and tempted by dark magic, Callum must stand against the rising darkness, but first, he needs to find the strength to face his buried anguish, even at the risk of fracturing what remains of his sanity. Yet, there is hope for a happy ending, if only Callum can summon the courage to accept it.
“I absolutely loved the 3rd book on the Callum Walker series. I had a hard time putting it down. I really want to know what happens next for Callum, Jax and some of the other characters. I love how the author creates and develops her stories. I can’t wait until the 4th book comes out ”_Guardian, Amazon Reviewer

About J.M. Shaw:
J. M. Shaw is a Canadian author of fantasy fiction who lives in Alberta with her husband and two young children. She’s been writing since childhood, building worlds from raw imagination and quiet observation, but it took years before she found the courage to share them. For Shaw, storytelling has always been more than a passion. It’s a compass. A sanctuary. A way to make sense of the chaos.
In 2019, Shaw was diagnosed with autism and ADHD, a turning point that brought clarity to a lifetime of feeling “too much” or “too different.” Her intense focus, emotional depth, and ability to live inside fictional worlds became not flaws but the superpowers of a neurodivergent mind. These qualities shape her stories, infusing them with realism, heart, and meaning, and giving her the courage to finally share her creative works. Her worlds may be fantastical, but her characters—flawed, searching, and deeply human—resonate on a personal level.
When she’s not writing, Shaw enjoys connecting with nature, curling up with a good book, and dreaming up new worlds. She also finds joy in encouraging young writers to pursue their own passions.
