Mercedes and the Waning Moon: The Dungeoneering Feats of a Discarded Vampire Aristocrat Volume 3

It's a new year at Edelrot Academy, and the students' first big test is to prove they can make the expedition from Abendrot to Blut on their own using nothing but the measly funds the academy provides. But halfway through the journey, Sieglinde(?) is attacked, and she and Felix are taken to the Beatrix Empire. It's up to Mercedes to save them, but what treasures will she recover-and more importantly, will Felix escape with his pride intact?
