Eldritch War Book 2 of The Supernatural Activities Division by William Stacey

After the ill-fated mission at Tora Bela, Wyatt and Haley Fowler have been side-lined by the Marine Corps. The Division, a secret force of special forces and mages that protect humanity from otherworld threats, recruits both of them. While they train for their new roles, a rogue mage is making plans of his own, which threaten everyone on earth.

Anyone who has read Stacey’s stories knows you can only hang on when you pick up one of his tales. The action is none-stop and brutal. His former military service plays a huge part in his stories and breathes authenticity throughout. I personally would love to play on a range with some of the weaponry that he introduces.
