Gamer Squad Series

Monsters Unleashed - where you catch virtual-reality monsters on your cellphone - is one of the hottest mobile games around, and Bex and Charlie just can't stop playing. They even check out an old map in Charlie's grandfather's attic in hopes of discovering some forgotten places in town where the rarest monsters might hide. But they find a strange machine up there, too, and after Charlie switches it on, the wifi goes down...and Bex's entire catalog of monsters vanishes!

After their scary adventure, Bex and Charlie have sworn never to play Monsters Unleashed again. Then Veratrum Games Corp releases a new augmented reality game featuring aliens instead of monsters, and the best friends just can't resist. After all, everyone loves it, even their science teacher, because it includes real star charts. But when they go to an observatory on a class trip, and open the game near a radio telescope, they get more than they bargained for: real aliens.

fter all they've gone through, Bex and Charlie have no intention of playing the new zombie game that Veratrum Games Corp just released. But everyone else in town is hooked, and when a flu sweeps the school, turning teachers and students into the undead, it turns out that only non-players are immune. Now, Charlie and Bex have to find a way to save their friends and neighbors - and stop the company from unleashing more of their deadly games.
