From my brothers Seth and Tom - if you have a blog, you can get both their books for free! Check it out. The following is from Seth Barnes' blog:

Tom Davis
and I are partnering together to provide a launching point for you to
find out what God has for you. If you've been a blog reader for a
while, we are offering our two books to you completely free of charge,
if you will do two things: listen and act.

My book The Art of Listening Prayer will teach you to better hear God's voice and build intimacy with the Lord, and Tom's book Red Letters will teach you about God's heart for the poor, along with practical ways that you can reach out to the "least of these."

After you read each book, we're asking that you post at least one blog
linking to our blog sites and drop a comment on this blog, letting us
know how it's going by answering these questions:

• 
  What did God move you to do?
• What did you learn from our books?

• 
  How did this make a difference?

We'll walk through this with you and help you discern what God is
saying and what your appropriate response is. So many people have a
desire to serve God and are virtually lost in a sea of choices. We want
to help you wade through all of that. If you're interested, act ASAP,
because there are only a limited number of books.
