Eventhough this book is the second in a series (of which the Dice Man was the first), you can easily read it if you haven't read the Dice Man before.
The story starts with Larry, the son of Luke Rhinehart (indeed, the author who also starred in Dice Man) who is successful in life and who appears to be happy...on the surface. Set on the track by an ongoing FBI investigation, he wants to find his father, who is presumed death. First to help the FBI and get even with his death who left him and his mother behind, then the actually find him. He decides that in order to find him he should live the life his father has...the life of living through the casting of dice. But this means ending his life as it was, and starting a new one...
The idea is that the character gives each roll of the dice a specific meaning, i.e. if he rolls 6 he should go out and drink three pints. Then by casting dice he determines what he should do, and if he rolls 6 he goes out and drinks three pints regardless of consquences.
This book is both moving and very funny, thought-provoking and balant and can be read as a novel of a young man searching his way through life.
If you liked the Dice Man, this is a must, if you haven't you can also try this one first and be amazed.
