I received a copy of this book for free for review.. I have not read book 1-4 but This appears to be the start of a Standalone arc.
A great start to a story and introduction the the world of Puatera Online. We follow Jessica on her not quite voluntary adventure. Great setting and story without the tropes of a Overpowered MC. While i would not consider this a whole story its a great start to one and will be diving onto book 6 with gusto,,
