The Netherworld Trilogy
When Halia and Xarun hear cries for help coming from their recently deceased friend, they must find a way to open a portal to the netherworld and send aid.
In a land ravaged by the awesome forces of nature, where homes and families are ripped apart by massive tsunamis and terrible earthquakes, a hero rises over the gale.
With dead bodies returning to life and demons roaming the land, Chara and Tyraz wonder what has happened to their friend, Jarlen, the only living necromancer. Not only might he be the one who can return the world to normal, but he might also be the one responsible for the problems.
