Reborn: Book 2 (Chronicles of Ghost Company)

When Bob leads elements of the Ghost Company through the tunnels of the Great Divide Mountain to meet with the Dwarven Council, he is unaware of a pending invasion of Curixeus, especially given the fact that they are busy fighting for their lives deep in the dark tunnels against goblin raiders.
Eventually, when the Ghost Company is sent to investigate claims made by fleeing refugees of giant cyclops ruthlessly capturing the king’s towns at ease, half of the lands have already fallen.
Will Bob and the Ghosts survive devastating losses to be able to help defend Prince Marcus's lands, or will the seemingly unstoppable cyclops armies and their local allies simply conquer all?
And what does the mysterious old man who is responsible for the earthlings being on Curixeus really want with Bob and the Ghosts?
