In the third book of Stephen Lawhead's Bright Empires series, Kit Livingstone's search for the Skin Map and the secret behind its cryptic code intensifies. Kit is beginning to master the ability to travel across realities using ley lines and has forged a link from the Bone House, a sacred lodge made of animal bones, to the fabled Spirit Well, a place of profound power. But there are darker forces at work in the universe whose agents always seem to be one step ahead of him and they're all desperate to gain the ultimate prize in this treasure hunt. Yet, what if this prize was not what he thought? What if the true treasure isn't the map at all? What if the map marks something far greater? Something one world cannot contain? The race is on to be the first to possess the map's secret for good or evil.
