Alien Survival

Rosa and Eddie are among hundreds of teens applying to NASA's mysterious Interworlds Agency. They're not exactly sure what the top-secret program entails, but they know they want in. Even if they are selected, they have no idea what lies in store. But first they have to make it through round after round of crazy-competitive testing. And then something happens that even NASA's scientists couldn't predict....

Cade Carter and his friends have survived the qualifying round of the mysterious overlords' twisted games, decimated by the loss of so many of their comrades during the fight. But they have no time to mourn, for the next round of trials is about to begin. When the group discovers that their next foe will be even more ferocious than the last, Cade leads them on a quest out into their strange new world to find anything that might give them an edge. But what they find in the wilds could prove to be even more dangerous than the impending battle....

Welcome to the new world. We thought we were the last and all we had to do was survive the initial outbreak. Turns out the hard part is surviving each other. Man, the post-apocalypse is brutal. Most of the runners have phased out, but a fraction have survived. They are smarter, faster, and way more deadly. We were supposed to be safe, but the virus has mutated, making the infected smarter than anyone ever thought possible. Our only hope for survival is to make it to the Tower, where we'll be safe behind walls with a group of survivors just like us.

Two boys and two girls are best friends. They have skied and snowboarded together into every corner of Jagged Peak in search of adventure, but always within the safety of that ski area's boundaries. Until now, when they follow the tracks of a strange snow-sliding creature into the volcanic out-of-bounds. And vanish into another world. Three land deep in an eerie jungle, and one falls high on an icy cornice - all of them ditched by a tricky, rogue wormhole, which disappears over distant snow-covered peaks.

Clover Martinez has always been a survivor, which is the only reason she isn't among the dead when aliens invade and destroy Earth as she knows it. When she hears an inexplicable radio message, she's shocked to learn there are other survivors - and that they're all at the former Area 51. When she arrives, she's greeted by a band of misfits who call themselves the Last Teenagers on Earth. Only they aren't the ragtag group of heroes Clover was expecting.
