Okay, so let's get started:
This book is...not good. I am one for long, flowy sentences, but there were so many times where unnecessary words were used. At one point, the author made the comparison "blackbird to an exotic bird". Why not say "peacock"? Things like that were so grating to me.
The book is very, very preachy. It is Christian lit, so I expected it, but it was heavier handed than I expected.
I realize I am not the target audience. Though I am a Christian, I do not normally read this genre. This book is definitely intended for those already serious in their faith. This is not a book designed to introduce readers to Christianity. It comes on too strong. For people wishing to fortify their own faith, it's fine, if you can deal with the poorly written prose.
