Logan's Journal: Companion to the 'Bloodlines Triology'. A Dead Hearts Novel

For seven hundred years, Logan Bennet was a prisoner of the ancient Greek god, Hades. Things can get complicated when time travel is involved, and an ancient Axon demon terrorizes the modern world by creating a zombie apocalypse. The powerful Earth Corps team members and human survivors in Colorado Springs believed Logan died in a battle fought against Lord Darkmoore, a wraith, during the 1340s in England.
However, Logan resurfaced in modern times as the Chancellor of the Blood Syndicate, an evil cooperation run by Vescali demons and vampires, to wage war against Commander Cadence, the Earth Corps, and the Pantheon of Light. Only Chancellor Logan is not the real Logan Bennet. Captured by Hades while trying to use a Babylonian Stone to return home, Logan spends his days in a winter landscape, in a cold, dark cell.
He is not alone. Hades is collecting old supernatural adversaries with the help of Vescali hunters from all over the world, and the prison is full. Time runs differently in this Hell dimension, and one day in Caceri is one day on Earth. Logan has nothing else to do but write about the horrors he experiences in a journal and hope someone might find it in the future and read what actually happened to him.
