Eternity’s Blade by William Collis is a fast-paced, atmospheric fantasy set in a world unlike any I’ve read before—a floating realm ruled by immortals, rituals, and war-torn prophecy. The story follows Soh’shoro, a prince whose mysterious ability to kill sets him on a path from royal life to trained assassin. What really stood out to me was the contrast between the lush worldbuilding and the raw intensity of the action. Collis blends mystical traditions with martial tension in a way that reminded me of Mistborn meets Shogun, and the result is both gripping and poetic.

While the novel is filled with explosive battles and political intrigue, it also quietly explores deeper themes like identity, loyalty, and the cost of legacy. Some of the emotional relationships felt a bit underdeveloped, but Soh’s personal transformation carried the weight of the narrative. It’s clear that this is just the beginning of a larger saga, with some questions intentionally left unanswered. If you enjoy immersive worlds, morally complex heroes, and stories that blur the line between destiny and rebellion, Eternity’s Blade is a debut worth diving into.

I received an ARC of Eternity's Blade from Netgalley.

The premise seemed interesting, but I was very confused with the worldbuilding, names, and terms. The ARC was also formatted oddly on my Kindle, so the reading experience wasn't pleasant.

I kept trying to give the story a chance to hook me, but continued to be confused by what was going on. It almost felt like I was dropped into the middle of a series with little to no recap.

No spoilers, as per usual.

In my uneducated opinion, it’s very high fantasy and whilst I enjoyed the vibe, the setting and the premise, I did struggle with names, remembering who was who, etc. However, this book was my first toe dip into what I’d class as high fantasy and the book length was great for me just beginning to expose myself to it. So this, by no means, is a negative about the book, just my lack of experience as a higher fantasy reader.

I won’t give anything away as I think this book deserves the attention of someone reading it without being spoiled the ending or characters etc, but I did love Soh’shoros journey and the world building was excellent.

I would most definitely recommend this book to others.

Thank you to William Collis, Blackstone and NetGalley for the ARC, and congratulations to William on a fantastic book.

An intriguing dark fantasy ripe with courtly drama and fantastic action, this one is sure to be a smash! Thank you to NetGalley and to Blackstone Publishing for a free ARC in exchange for an honest review!

Found this book to be pretty average. The writing was serviceable, but I never felt much connection to the characters. The action was interesting though. And I thought the last third was the best parts. I would read another book by the author.
