All three books in the Surprised by Truth series highly recommended. These are personal stories of conversion, and these converts describe the struggles they had with the claims of the Catholic Church. Various backgrounds here: Anglican, former Catholic "reverts", Baptist, Reformed, etc. The apologetics was a little stronger in the first book of the series, but all three are great books. For books with stronger apologetics content get A Biblical Defense of Catholicism by Dave Armstrong, or Steve Ray's book of conversion Crossing the Tiber.
To see and hear many of these converts in person, you can check them out on the Journey Home program from EWTN. Wonderful and impressive given all they had to go through to find the truth.

Like the first two - this is a very moving book. Born Catholics will be amazed at how difficult it is to make the final step. Moving and inspiriational.
