Halley's Bible Handbook is a good 'companion' when you are first getting into the Word. Not much 'opinion' if any, and it's nice to get a little background on each book before you start in...things like who probably penned it, who it was written to and why, where the author was when he wrote it etc. ya know, the basics.
I also liked reading apologetics along side The Bible, especially at the beginning when my faith was more fragile and I needed some solid defense against some stories or passages that I found pretty unbelievable at the time. Apologists don't usually delve to far into their opinions on doctrine, but more the philosophy behind faith and the facts surrounding the Bible.
If you are interested in some good apologetics you can search this board for recs and get all sorts of wonderful direction.
My personal favorite is still Ravi Zacharias...but there are many excellent Christian Apologists to choose from.
