Dark Moon: Book 1 of the Brotherhood of the Moon

Throughout Time mankind has believed that they were alone in the universe. Then, one fine day, the invasion came. A massive alien ship descends on the scenic New York sky line, mercilessly massacring people by the thousands with blinding, electric blue beams of light. America's Armed Forces fearlessly engages the alien ship , throwing everything they've got at it, missiles filling the sky, the hundreds of explosions making the hull of the alien ship look like the surface of the sun. Unknown to the soldiers attacking, the alien's ship has impenetrable shields that destroy humanities hopes for victory even as their armies, navies and air forces are annihilated in blinding flashes of blue light. Now, only scattered special forces and the reemergence of beings out of the darkest human legends are all that stands between the aliens and the complete destruction of the human race.
