Gravetide, livre audio

Jensen is in trouble.
Graves are being robbed, and it looks like it’s for the Gravetide ritual, a spell so powerful that if invoked correctly, will give the caster absolute power over the five elements of magick.
She is from a long line of gate guardians and the last time the Gravetide ritual spell was cast, her ancestor died to prevent the spell from manifesting. Unfortunately, the secret to the counter spell died with him.
The worst part is, it looks like an Arch Demon is casting this. She has six days, six hours, and six minutes to find the castor or the world of magick and men will cease to be the same. Forever.
She is about to find out what kind of hell a demon can bring to Earth.
