England, 1923. The Great War is over, the Twenties are roaring in, the Bright Young Things hold ever more extravagant parties. It seems as though the world has changed for good. But some far older forces are still at work, and some wars never end.
The occult battles fought in the War Beneath the War have torn the veil protecting our world from what lies outside. With most of the country’s arcanists dead, and the Government unwilling to face the truth of the damage done, a small group pledged to an ancient duty must protect England from supernatural threat.
Set in the world of the award-winning Secret Casebook of Simon Feximal, the Green Men series covers a motley crew of occult experts, jobbing ghost-hunters, and walking military experiments as they fight supernatural and human threats, save the land, and fall in love.
