Hugh Howey, the author of the Wool series that I love and reviewed a few months ago, is a master of creating interesting realities.
Howey's The Plagiarist is the tale of a college professor who moonlights prospecting virtual worlds for great works of art and literature. The moral quandaries, his love life and general lack of mental health all blend to tell an engrossing tale.
As usual Howey's work is hard to put down. If you enjoyed Wool, be sure to read the Plagiarist.
