Dig Deep! The Rangers Are About To Set It Off!
What starts as a mission to control a key area of a city under siege becomes a relentless race against the clock for Ranger Team Leader, Louis Campbell. One minute Lou and his team are fighting Saur infantry looking to stab them in the face, and then next, he's saddled with a bunch of dwarven sappers who must breach the city's catacombs. And they need his help to do it!

But the Under Roads are no simple tunnels, and these are no simple dwarves. Dispatched by the dwarven king, the Ax Rider and his crew demand Lou help them, or the defense of Sûstagul could be lost in a tidal wave of undead.Using cunning, modern weapons, and a bit of dwarven know how, Lou and Ax Rider must negotiate the alien underground landscape to their target, an engine of malevolent power known as the Underspire.

In the war for the Ruin, some battles must be fought in the dark!

This stand-alone novel is set between the events of Forgotten Ruin Books 6 & 7, but can be enjoyed without having read them. The Siege on Underspire takes you beneath the streets, to fight the battles you didn't see coming. Grab your rifle and unsheathe your ax to join Louis and the dwarves in their bid to shatter the Underspire before it's too late!
