Christopher Kaczor has just published a new book entitled “The Ethics of Abortion: Women’s Rights, Human Life, and the Question of Justice.” http://www.amazon.com/Ethics-Abortion-Question-Routledge-Bioethics/dp/0415884691
This is an excellent book, and I highly recommend it. In the book, Kaczor defends the pro-life position with clarity and philosophical depth. Nearly half of the book discusses the personhood question. He also critically discusses the most recent defenses of abortion rights.
