Lunar Patrol: Hunter Squadron

Lt. Liam Turner, USCG, is finishing his flight training in Pensacola, Florida, when he is approached by Paul, the liaison with mysterious aliens who have been guarding Earth for centuries. Invited into a world he never knew existed, he discovers the universe is full of intelligent life, and not all of it is friendly. Having barely learned to fly a turboprop, Lt. Turner has to learn to fly a space fighter and assemble a squadron of fighter pilots to defend the Earth from an approaching alien armada.
