Altina the Sword Princess: Volume 12

Now thought to have been assassinated at the second prince’s order, Regis returns to Verseilles in disguise. There, he unites with an unexpected ally, enacting a plan to sow political discord. In the midst of this covert operation, Altina leads her army to the capital where she at last reunites with her tactician. There is no time to rejoice, however—tensions linger, and a new emperor soon takes the throne. Latrielle issues a declaration of war to all surrounding nations, and Altina is dispatched to the disastrous southern front. Here is the twelfth volume of a tale of war, love, and politics, woven by the bookworm and the sword princess.
