Captain of the Guard (The Second Son Book 1) by Ron C. Nieto

Oren Trevaine has never shaken the feeling that he’s not good enough, but he’s determined to avoid the same fate for his men. Oren’s first task as Captain of the Guard is to transform his unruly, undisciplined soldiers into a formidable army—if only they would cooperate. But Oren will need to act fast because the snow is melting with the budding of spring. Soon, the enemy will be able to traverse the main pass through the imposing Sansford Range and his men must be ready to patrol the mountain. When Oren rescues Lady Joan and her traveling party from a band of Mirdoni raiders, his worst fears are realized. The enemy has utilized less accessible routes to infiltrate their territory, and an attack is imminent. Now Oren must not only think like the enemy, but he will need to be one step ahead. With the kingdom relying on him and Lady Joan promising her favor if he returns alive, Oren will need to prove to her and his men that he truly is good enough. Or at the very least, die trying . . .
