On the wild west coast of Ireland, a neolithic burial chamber is uncovered. Inside, and perfectly preserved, is the image of a fabled Nemean lion and its cub drinking from a bubbling fountain of pure fire.

The image matched the one found on an ancient scroll that warned of a Celtic Prophecy. It foretold of an approaching disaster of unimaginable scale hurtling toward the modern world… Sam Reilly needs to solve the Celtic Prophecy and find the fabled Nemean Lions, whose secret may be the only thing that can save his life.

Racing from Ireland’s peat-laden vaults to a sealed druidic chamber hidden beneath a basalt sea cave, Sam and his team must piece together the lost prophecy before its final verse becomes reality.

The past is calling.

And its secrets may cost the very future Sam Reilly’s trying to protect.
