I read some of this book called Geula B'Rachamim(redemption with mercy) by Pinchos Winston, and definitely recommend it. The author's words enhance the shemona esrei prayer so we say it with more meaning. Plus, the book overall generally helps to yearn and look forward to the future. He mentions toward the end of the book that to bring the redemption closer, we have to really show we want it.
You know how people get comfortable where they are and don't really feel a need for change. However, we really need this. And he says that we should seek it now, rather than when you are desperate.
Our prayers can really make a difference.
