“The girl who swims between worlds shall drown.”

Kevin Cox


A huge thank you goes to Kevin Cox, for giving me an opportunity to read Eternium! This is the finale to the YA fantasy/sci-fi Bewilderness series, and it’s hard to believe we’re already saying goodbye to Ambrielle. But rest assured dear bookworms, it’s everything we could’ve hoped for when we first joined her on this adventure! If you haven’t seen my reviews for the previous books? You can check them out here. Now let’s give you an overview, shall we?

Ambrielle and her ragtag crew think they’ve finally found a way to get rid of the Shadows, not only in one world but across the universe. Yet the people who could best guide Ambrielle and her friends on this quest? They have no way of journeying alongside them. Relying on vague instructions and the guidance of her own instincts, can Ambrielle save everyone before it’s too late? What secrets might tear this mission apart? Is it even possible to survive against the might of their enemies?

This is such an exhilarating finale to Bewilderness!

Happiness Boost:

Eternium is an incredible finale to the Bewilderness series, and easily navigates between different POVs to give us an immersive experience. This has truly been a coming of age series, and with this final tale? Ambrielle’s now become a level-headed, strong woman who surrounds herself with indomitable friends. There is nothing she wouldn’t do for them, and with her ability to persist in the face of danger? That’s a huge happiness boost for me!

Kevin’s introduced some wonderfully disturbing elements within this instalment, and I *love* that. Is it weird to count a sentient, bloodthirsty sword as one of my happiness boosts? Probably! But I’m still adding it. I couldn’t help but think of R. A. Salvatore’s Drizzt saga , as well as J. V. Hilliard’s The Warminster Series. It’s a devious, terrible power and I was so invested in how Gavian would fare against this insidious threat.

Wegin has to have it’s own happiness boost once again! I know I shouldn’t, as I’m sure people will be wanting to know all about the actual plot and technical aspects of Eternium. But in my domain? I’m not bothering with that. This little robotic companion is such a humorous addition to the group, and I honestly think it’s desperately needed to create a lightness to the story. Without Wegin? It would be a bleak adventure this time around, as the worlds have become a desolate place. We all know humour is essential in such times!


Although this instalment feels like it’s more influenced by the sci-fi genre than fantasy (which we all know isn’t my preferred genre), I still really enjoyed myself! Just be prepared for this and you’ll have fun, I promise.

Eternium by indie author Kevin Cox is the incredible finale to the YA fantasy/sci-fi series, Bewilderness!
