Citadel of Smoke (Stonehaven League #4) by Carrie Summers

 Epic!

This is the showdown that has been building as Devon and her allies fight to save Owen, both from a rogue computer entity and his own father’s political game. To do so, Devon must strengthen her dark powers and descend into the dimension of Hell and bring the fight to the evil Zaa and her band of Demon Lords.

A futuristic look at online gaming that allows full immersion into the gaming world. But when there’s a computer glitch, it creates an enemy that can cause real harm to the players. There’s no escape. You must fight. You must win!

Ms Summers once again shows that she is a master storyteller with a fantastic concept, suspense, massive battles, humor and the talent to pull it all together.

Loving this series.
