While the book does take quotes from Rob Bell's Love Wins, which presents a universalist view of hell, this is not a book slamming Bell or his work. Not at all! I would imagine Bell's book played a roll in this project coming about, but it is not the central catalyst. I stated earlier this is a look at the Truth... the Word.. what God has to say about hell.
I have read it through once... reread parts... and have no doubt I will read it again. I suggest keeping a Bible close at hand as you read.
Ultimately... before all is said and done, this is a book on the Sovereignty of God. And that, for me, is the best news of all!
