These collections feature three books, including Accidental Trouble Magnet, Unexpected Super Spy, and Incredible Rescue Mission. The Incredible Rescue Mission features some pretty deadly aliens! When Omar and his friends come back after the school holidays, their lovely teacher doesn’t quite seem herself. It seems as though she has been replaced by somebody much more grumpy. Overhearing other teachers talking about her, Omar comes to the horrifying conclusion that something terrible has happened to her. Could she possibly have been abducted by… ALIENS? Omar must persuade his friends to mount a rescue mission, but what they find is very surprising…

Alien Books for Older Teens and Adults

Alien Books for adults and teens are far from cute and cuddly and more blood-thirsty and spine-tingling, much like the best-selling Alien franchise 7 series books collection set by James A. Moore and Tim Lebbon. In the 20th century, all Alien-related books were published as adaptations of pre-existing material from the novelisation in 1979. This collection includes Alien: Out of the Shadows, Alien: Sea of Sorrows, Alien: Rover of Pain, Alien: Invasion, Alien: The Cold Forge, Alien: Isolation and Alien: Prototype. The novels tell of a group of miner harvesting trimonite, the hardest material known to man, on Planet LV-178. An unexpected discovery deep within the mines leads them to uncover the ruins of an ancient civilisation infested with Xenomorphs, a vicious and predatory extraterrestrial species, that infiltrate the miners’ ship. Protagonist Ellen Ripley picks up the distress call and is left to help the miners survive the Xenomorph's brutal attack and help them escape. 

Looking for more young adult science fiction novels about Aliens? Look no further than The 5th Wave by Rick Yancey. Now a major motion film by Sony Pictures starring Chloe Grace Moretz. The story follows sixteen-year-old Cassie Sullivan as she tries to survive a world devastated by waves of alien invasions that have decimated the Earth’s population. During the First Wave, the Others released an EMP wave taking out all electronic technology and killing half a million people. The Second Wave caused massive tsunamis that wiped out the population living around the coastlines. The Third Wave infected the remaining population with a deadly virus, causing the victims to slowly bleed to death. The Fourth Wave: silence. And now, the Fifth Wave, where young Cassie must do all she can to survive the final attack from the Others. This book is perfect for fans of The Hunger Games, Divergent and The Maze Runner series.
