Deep within the bowels of Northern Norway’s Segla Mountain,
ancient darkness stirs — and Echo Team is not prepared.
A Scandinavian hunter’s teenage daughter is kidnapped. His wife is brutally killed in a home invasion. When the police investigation fails, Sigurd Martinsen is connected to Echo Team — a classified NATO special-ops unit operating on the edge of the known world.
What begins as a rescue mission unravels into something far older and more terrifying. Echo’s discoveries reach beyond Russian-backed militants into an obsolete, Nazi-built tunnel network carved beneath Segla Mountain during World War II.
And deep in those tunnels, something has been waiting.
Old Norse legends ignite. An army of trolls guards the mountain’s bowels — ready to kill every last intruder. Sigurd and Echo Team must fight not just for a missing girl, but for survival against forces no modern weapon was designed to stop.
