The final volume of the Feldsher's Apprentice trilogy.

The year is 1645. A murderous war has been raging through Central Europe for 28 years, and there seems to be no end in sight.

After the death of his master, Martin, Gustav is left with nothing. Only Anike is there to console him over the heavy loss. When she asks him to help her possessed father, Gustav realizes that the key to helping her—Martin's Codex Daemonum—makes no sense to him. He must first complete his apprenticeship to be able to decipher the mysterious book. Torstensson finds him a new master, but the man only wants to kill Gustav. A reckless game begins in which everything is at stake.

"Take care of yourselves! Your beautiful Mela won't always be there in time to save you. The real war is just beginning."
