Warlord of Gambria: Misfits of Gambria (Book 10) - Misfits of Gambria, #10

Alric's reign as king didn't last long as Pavia decided he was in the way and permanently removed him. Yet her position as the sole ruler and Queen of Gambria is far from secure and her paranoia grows with each day. Rhosyn, her most trusted confidant, the woman who knows all of Pavia's dark secrets, has gone missing, and Duncan, the main threat to her reign, has refused to disband the Templars, making him the most powerful Lord in the Kingdom.
And now the Rugian army is maneuvering through Grimnost Forest, hoping to catch Gambria unaware. Deciding to solve two problems at once, Pavia orders Duncan to stop the Rugian invasion, hoping he will fail and get killed in the process. Either way, should he return from battle, he will find that his commanderie has been given to another, Lord Cedrych, who believes Duncan was indirectly responsible him losing his commanderie to Menec and has plotted his revenge ever since.
As it stands now, the future of Gambria is in Grimnost Forest.
