I am reading this great book right now. The book is called Lamb: the Gospel According to Biff, Christ's Best Pal by Christopher Moore.
If you don't like your Jesus stories told irreverently, don't bother, but if you think there is more to the story than we've been told or if you have heard and like John Prine's "Jesus, The Missing Years" you are gonna love this book. It's funny. It's told from the perspective of Jesus' childhood friend and from the perspective of this same person who's been dead for 2000 years. It's insightful. The purpose seems to be to flesh out the years between Jesus challenging the Pharisee and his return to be baptized. It makes Jesus into a real person not a mythological character...he thinks, he feels, he wonders, he has friends and family.
I don't know if it's completely accuate, historically, but it works for my level of knowledge of the history of world in that era. Like I said it's quite irrevernt but it maintains the general principal all Christians believe - Jesus was the Son of God and the Messiah.
