Of Jenny and the aliens

Ten years after Earth sent messages out into deep space, there has been an answer. Music from a distant planet has reached our radios. Are aliens about to invade? No one knows, and almost-eighteen-year-old Derek doesn't really care, because at a wild end-of the-world party, Jennifer Novak invites him to play beer pong, and things ... progress from there. Derek is in love. Deeply, hopelessly in love. He wants it all - marriage, kids, growing old on a beach in Costa Rica,. Jenny is the One. But Jenny has other plans, and they may or may not include Derek. He'll try anything to win her - even soliciting advice from an alien who shows up in his hometown. This alien might just be the answer to Derek's problem. But is Derek willing to risk starting an interstellar war just to get the girl? And just how far will he travel to discover the mysteries of the universe - and love?
