Dodge Tank

"There’s only one rule … don’t get hit."
Ryan’s life sucks.
His brother is a jerk, his mom is sick, and his legs are next to useless thanks to a neurological disorder. Plus the world ended two centuries ago from nuclear war. Now, what’s left of humanity live below ground, with the only escape from reality being the massive VR world of Crystal Shards Online.
But even in the game, Ryan’s life sucks. Unable to play a combat class due to his condition, he works as a miner, earning barely enough to get by and not nearly enough to afford the operation that will save his mom’s life. 
When Ryan discovers an item that grants the ability to dodge any attack, however, he has the chance to become one of the game world’s most elite and sought after players: a Dodge Tank.
But for someone who’s never played a combat class, success isn’t so easily had.
To save his mom, Ryan will have to overcome his disability and level his way to the top. But the real-world consequences are more far reaching than he ever could have imagined and the fate of not just his mother, but humanity itself, may be resting in his hands.
