Hellbeast [EPUB ebook] 

Heroes don’t always walk in the light.
The fate of the world is balanced on a knife’s edge. Despite everything Madden and Eva have been through to prevent it, the ARC Council is in disarray and demons roam the Earth.
The Apocalypse is closer than ever, and the solution couldn’t be further from her grasp. Eva has to throw off the yolk of personal tragedy and follow her destiny to the one place she doesn’t want to go.
The one place she cannot hope to avoid.
