The Revenant's time

If you don't know what a revenent is it, is a human who came back from the dead by the power of a necromancer intent on one thing, killing those who wronged them. It has all the memories and abilities of it's previous life and an extreme skill in warfare. In this book an extremely powerful necromancer brought back thousands of revenents and put a curse on them whomever they kill becomes a revenent as well and they attack indiscriminately instead of those who wronged them . Join this party of heroes Thana-the witch Jivana- the swordsman Belial- the archer and Sozeal- the cleric on their epic quest to kill the necromancer.
