The Doors of the Sea by David Bentley Hart, from an Orthodox perspective.
The Justification Of God by John Piper, from a Reformed perspective. This book is more focused on the question of how can God be called good if he has sovereignly ordained that some people be damned, but the existence of God is clearly an implication of that question. As it's written by a Reformed theologian you can't be quite sure that the answer isn't "because freedom!"
