Threshold

After a terrorist attack on a reservation in Oregon leaves thousands dead, Jack Sigler, callsign King, and his team must protect the only survivor, thirteen-year-old Fiona Lane. When a death in the family pulls King away, and the rest of the team is sent on a mission, Fort Bragg is attacked by a strange and overwhelming force. When the dust settles, Fiona is gone...

But the attack is part of a larger offensive. Around the world, the last speakers of ancient languages are being systematically exterminated. As they fight to find the mastermind behind the killings and Fiona's kidnapping, the team is hunted by strange creatures that defy explanation―living statues, genetically-modified monsters, walking megaliths―sent by an enemy from their past. If not stopped, he will be able to remake himself, and the world.

Calling on help from old friends and ancient heroes, the team fights their most desperate battle yet, not just to save the world as we know it, but to rescue a little girl who wants nothing more than to call King 'Dad.'

An ancient tower holds the key to unlocking a horrifying secret hidden within mankind's most antiquated languages. If the secret is unlocked, the world as we know it will cease to exist.

International bestselling author Jeremy Robinson's third book in the Jack Sigler series is a rocket-powered thriller, combining high-adrenaline action, smart science, ancient legends, and stunning locations.
