I just read Alterworld on Kindle, and it's sequel The Clan. Very good books, and the 3rd is coming out around New Years. Very similar in style to the Light Novels Legendary Moonlight Sculptor and Ark, which I'm also reading as the chapters come out.

As for what they're about...

LMS:
The man forsaken by the world, the man a slave to money and the man known as the legendary God of War in the highly popular MMORPG Continent of Magic. With the coming of age, he decides to say goodbye, but the feeble attempt to earn a little something for his time and effort ripples into an effect none could ever have imagined. Through a series of coincidences, his legendary avatar is sold for 3.1 billion won, bringing great joy to him, only to plunge him into despair at losing almost all of it to vicious loan sharks. With revelation of money through gaming, he rises from the abyss with new found resolve and steps forward into the new age of games led by the first ever Virtual Reality MMORPG, Royal Road. This is the legend of Lee Hyun on his path to becoming Emperor with only his family loving heart, his boundless desire for money, his unexpected mind, his diligently forged body and the talent of hard work backing him.

Ark:
Kim Hyun Woo lived the life of the wealthy thanks to his parents. But one day, he received a phone call informing him of a traffic accident which involved them. His father had died and his mother was hospitalized in critical condition. The normal life he once knew collapsed...

They sold their house, canceled various insurance plans, and moved to a one room apartment. And after a few years, Hyun Woo was spending four to six hours tending to his mother and worked to pay for her medical bills.

One day, one of his instructors recommended him for position in a company called Global Exos, which made an announcement of making history with its newest technological invention.

Alterworld:
A new pandemic - the perma effect - has taken over Earth of the near future. Whenever you play your favorite online game, beware: your mind might merge with the virtual world and dump its comatose host. Woe be to those stuck forever in Tetris! And still they're the lucky ones compared to those burning alive eternally within the scorched hulls of tank simulators.

But some unfortunates - the handicapped and the terminally ill, shell-shocked army vets, wronged crime victims and other society misfits - choose to flee real life willingly, escaping to the limitless world of online sword and sorcery MMORPGs.

Once a seasoned gamer and now a terminal cancer patient, Max grasps at this final chance to preserve his life and identity. So he goes for it - goes for the promise of immortality shared with a few trusty friends and the woman he loves. Together they roam the roads of AlterWorld and sample its agony and ecstasy born of absolute freedom.
