Operation Bounce House

All colonist Oliver Lewis ever wanted to do is run the family ranch and keep his family’s aging fleet of intelligent agriculture bots ticking. But when his planet's transfer gate finally opens and restores instant travel and full communication between Earth and his planet, New Sonora, there’s a complication. The colossal Apex Corporation is hired to commence an “eviction action.” and they charge bored Earthers for the opportunity to design their own war machines, remotely pilot them and make it a game. Oliver and his friends soon find themselves fighting for their lives against these machines. But with the help of an old book from his grandfather, Oliver is determined to defend the only home he’s ever known.
