The great stone face

I read the book of ladder series again and this time I chose level one.This book is level one so first I thought this book is very easy and I can finish quickly.However, it took two days to finish reading.This book is level one but I think it is more difficult than other series of level one book.
Next I want to talk about outline of this book. There was large rock look like human's face in the ravine, also there was a legend that person who born in this village will come back to here after become a great person.The hero called Ernest was waiting for a legendary hero.One day three menn who made themselves immortal. Are these men legendary hero? If so, which man is legendary hero?
I think reading difficult book many times make you reading book boring.I consider that reading easy book sometimes is good for you to a change of pace.
