Wake the Dead by Jocelynn Drake

The dead wait for Caelan.
The Goddess of Life has sent Caelan to wake her brother, the Dead God.
But crossing the reclusive country of Zastrad is even more treacherous when Caelan and his friends aren’t sure they can trust their guide.
The four friends will be tested by violence, death, political intrigue, and secrets better left in the dark.
When Caelan finally reaches the fractured godstone, he may have to give up everything to save the family he’s cobbled together
