The Women's Bible Commentary is a trusted, classic resource for biblical scholarship, written by some of the best feminist scholars in the field today. This twentieth anniversary edition features brand new or thoroughly revised essays to reflect newer thinking in feminist interpretation and hermeneutics. It comprises commentaries on every book of the Bible, including the apocryphal books; essays on the reception history of women in the Bible; and essays on feminist critical method. The contributors raise important questions and explore the implications of how women and other marginalized people are portrayed in biblical texts, looking specifically at gender roles, sexuality, political power, and family life, while challenging long-held assumptions. This commentary brings modern critical methods to bear on the history, sociology, anthropology, and literature of the relevant time periods to illuminate the context of these biblical portrayals and challenges readers to new understandings.

Mere Apologetics: How to Help Seekers and Skeptics Find Faith by Alister McGrath is $3.99 at Christianbook and Amazon. It's $4.99 at Kobo, but couponable.

Edit: I bought The Women's Bible Commentary and started to look through it and I'm very excited to give it a more thorough read. The commentaries are thoughtful and approach Scripture with a point of view that's often ignored. I was concerned that the "feminist" descriptor meant that the commentary was an attempt to rehabilitate the Bible from its male centricity, but instead the commentators are more interested in exploring the attitudes of the Bible writers (both assumed and explicit) and how those helped shape the text as we have it.

Be aware that the commentaries (that I read so far, at least) are not written from a theologically conservative point of view. This selection from the commentary on Exodus, for example, is typical:

While ancient Israelite religion is often considered to be a form of monotheism, in some sense it might be better thought of not as strictly monotheism but as monolatry. Monolatry is the worship of a single god while acknowledging the existence of other gods.
