Sara is one of the cool kids; she's got the right friends, makes the right jokes... and is totally terrified of losing her status. She'd be a lot more secure if she could win back her super-hot ex, Skyler, but he's not interested unless they move to the next level. Sara decides to take the plunge without protection, but soon discovers Skyler isn't just like a normal teenage boy. Something changed on his summer trip to Mexico. Something... extraterrestrial! When Sara wakes up the next morning nine-months pregnant, she turns to the only person she can trust: her nerdy ex-best friend, Hayley. The girls soon realize this alien problem is only just the beginning. Ultimately, this is a story of a teenage girl finding her self-worth and learning to accept her choices... by killing aliens and saving the world!
