I have only read four chapters so far. It looks like this book is a thrilling fantasy - a metaphor of choices and their consequences.
On chapter 16 I see the road to hell is inundated with warning signs, but is seems like only those who have their eyes opened to see the signs get the full benefit of them. With the warning signs along the road, a friend comes along to show the way off the road to hell. I hope Luke grabs his hand and runs, with him, to the "light at the end of the tunnel". I won't tell you when I find out, but I will tell you this book is well written and worth reading.
