Burning Question: Are You Trying to Tell me Something?

So during my morning reading time I was reading a Christian book that quoted a book called Half Time. This intrigued me but I went on. Later in the morning I was reading a separate book and it referenced and quoted Half Time as well. So the question is, is God telling me to go read this book as well? Or perhaps the bigger question is, does God use books other than the bible to speak to His people?
