Game Night is a fun book by Johnny Nexus. The core concept is very familiar– a dysfunctional RPG night and pokes fun at the problems common to RPG groups (much like the movie, The Gamers). Time starts and stops, rewinds, and one character just stands around because its player is asleep all the time.
A conceit of the book is that the players are gods guiding their mortals, not strictly roleplayers. The book’s humor runs well throughout, even as he needles our foibles.
If you’re interested in giving it a try, the author just released a free novella length prequel as a teaser. It’s called Saving Stone.
