I gave this novel 4 out of 5 stars on Amazon and 3 (3.5) on Goodreads!
The Rage Within is a book full of unique creatures and the main character's (Kellan) "flaw" is intriguing. The story was a good one that kept my attention throughout. While some cliches were in play regarding main characters, the brooding protagonist, the great and selfless friend, and a band of comic and harsh misfits they were done well and did not distract from the enjoyment.
Some of the enemies were very well done and I enjoyed many of the fight scenes. The only true negative, other than the minor typos here and there, was the story flow. The book's chapter flow between the Kellan of now and the Kellan as a child and his journey to adulthood. While the idea was good, to have two timelines that converge over time, it was a bit confusing at times.
Overall, I enjoyed the book and would definitely read more from the author. I recommend to fantasy readers that like detail, a strong story path, and a likable but dark protagonist.
