Review: Obsidian Sky

Book Review: Obsidian Sky, by Jill Aster, 1 star

 

Thaelyn Marren enters the Asgar Training Academy wanting nothing more than to prove herself amongst the other cadets, where she must endure life-threatening trials in the hope of manifesting air, water, fire, or earth magic. Not to mention, a lucky few will pair with dragons who select their riders with ancient instinct, answering only to those whose souls burn bright enough to match their own.

When Thaelyn’s power stirs in ways no instructor can explain, she draws the attention of the crown, particularly Prince Thorne Dareth, a renowned warrior and a dragon rider. Hardened by discipline and haunted by a kingdom he was born to serve, Thorne sees Thaelyn as a danger to the realm and yet is charged with her training. And amidst clashing personalities, an undeniable pull forms between them, potent enough to awaken dark forces that once tore the world apart.

Now rift-born creatures thought to exist only in nightmares are slipping through the cracks of their reality. And as they push the realm toward open war, Thaelyn may be the only one able to stop what’s coming. That is, only if Thorne can choose between loyalty to his crown or the girl whose power could either save their world or bring it to ruin.

Review: When I picked up this book I was already aware the plot was an imitation of Fourth Wing. And I still decided to read it because, while for me Fourth Wing is in a category all of its own and Xaden and Violet will always have a special place in my heart, I really didn't mind revisiting a similar plot, if it was well written. 

It's not. Well written that is. There's no world or character building, the writing is repetitive (literally, in places), the constant point-of-view changes are confusing, and some parts of the story do not fit in with the rest just because the author is dropping words and concepts from Forth Wing into the book, without the proper follow through. The whole thing deserves better writing and better editing. 

So, unfortunately, I found myself very disappointed after reading Obsidian Sky and there's little I would recommend about it, other than the cover (which is really pretty). There's to be a sequel (of course there is), because the book ends at a cliffhanger (of course it does) but I don't think I'll want to read it any time soon. 

Happy readings!
