Onslaught (Last Life Book #12) by Alexey Osadchuk

Ricardo di Lorenzo, the renowned Golden Lion, is irritated by the delays his campaign is facing. King Adrian presses him to move; tension is rising among the nobility due to the machinations of the Scarlet Order; and the threat of insufficient provisions makes every wasted day a direct blow to discipline in his legions. More and more often, Ricardo finds himself thinking about the offer from Olgerd III's messenger. Meanwhile, Carl III and the rest of the capital wait impatiently for news of a pitched battle between the Vestonian Coalition and the legions of Otto II. After all, the outcome of that battle will determine the balance of power on the continent. For his part, Max has managed to halt the advance of the Atalian forces. As the Golden Lion's legions disperse into winter quarters around Conterne, Max returns to Fort de Gris, in order to marshal his forces and take command of a united army of first-born, true gifted, and humans. The onslaught is gathering strength... The battle for Northern Bergonia is coming!
