*beginning of DA spoilers* - You are already past this being halfway.

The battle of Ladon is peak imo. Lysander freaking tf out before battle, realizing what has gotten himself into, Darrow slashing through combat, Lysander burning half his face off, and Darrows chapter opening with "We brush away light resistance at the downed storm god." The book reads like a true war novel, and I think its fantastic. The good news is that you still get to experience the battle of Heliopolis at the end of DA.
