Whispers of the Past by Shawna Hunter
A coven of college witches heads into the woods on Halloween night.
They go intending to contact the ancient spirits who can help them unlock the power to make their dreams come true and they succeed.The wisdom of the past, however, comes at a price and the coven soon learns that failing to recognize what one is given drives that price higher.
Now, having transgressed and offended the ancients they will have to take what's coming to them. The ancients, however, are not perfect and even they can be corrupted. The coven came to listen to their whispers but in return they will have to give their bodies over to powers that have never experienced the pleasures of the flesh.
