Good General Introduction to Orthodoxy Books

• The Orthodox Church - Bp. Timothy Kallistos Ware (can be found online here)
  The Orthodox Way - Bp. Timothy Kallistos Ware
  
• Eastern Orthodox Christianity: A Western Perspective - Daniel Clendenin

Other books:

• Father Arseny: A Cloud of Witnesses, translated by Vera Bouteneff
  
• The Arena, by Bp. Ignatius Brianchaninov
  
  • I've been told that Fr. Thomas Hopko recommends this book for everyone.
• The Way of the Ascetics, by Tito Colliander (can be found online here.)
  

Also, I would recommend that you check out the many programs at Our Life In Christ. They are a very good resource to learn about Orthodoxy.

For more information, there are a number of online resources for studying or learning about Orthodoxy. A number of Orthodox blogs are listed on the sidebar to the left of this site. Out of these sites, in addition to the ones already referenced above, among my top recommendations are:

• the writings of Fr. Stephen Freeman
  
• the Word from the Desert blog
  

In the end, though, one can only learn about Orthodoxy through these sources. What is more important is first-hand experience of Orthodoxy, and this comes from taking part in the life of the Church. (attending church, fasting, praying, etc.)
