The only book that could connect you with God would be the Bible, continued studying and habitual reading can help you learn better. As the word of God there is 100% chance you will find accurate knowledge. The thing about studying is how much you want to learn and choosing the Christian form of worship because that is the way of Jesus Christ, 1 Peter 2:21.
To connect with God through nature is for experienced learners with modern questions that explain natural process. Some believe yoga is the way, but nature means through science. If that is the mature way then science can tell you the natural things that are not revealed but are present, for example how were the clouds formed? There is nothing wrong with consulting scientific discovery, it does not offend God to ask questions respectfully. The Bible does have scientific information in it, our faith is surely strengthened by understanding the things that were created, Genesis chapters 1-3.
