Two books worth reading:
Seeking God in Science: An Atheist Defends Intelligent Design by Bradley John Monton
is carefully written, really objective, with plenty of critique for the mindless anti-ID crowd, plus interesting observations on some of the ID arguments. Very informative.
Signature in the Cell: DNA and the Evidence for Intelligent Design (Hardcover)
~ Stephen C. Meyer
is a voluminous defense of ID based on the information in DNA. The presentation is very low-brow, and very repetititive. But it is very thorough, refuting the vast majority of complaints against ID - both scientific arguments and philosophical arguments. As a guide to some of the latest research it is fascinating. I have a couple of qualms with the arguments, but I am not sure I am right.
