You Brits must be much more avid readers across the Pond… I can’t imagine any 5-week group in America getting a “book list” (not just a book) unless it was a college course!
Would you like chapter recommendations, so people don’t have to read entire books?
With that in mind, I wondered if someone who has read The Lost World of Genesis One (by John Walton) could weigh in to suggest perhaps a chapter or two in it? That seems to be the go-to book around here to understand Genesis in its historical context. The benefit of it, of course, is that you don’t have to haggle over the details of the science. If people can get a vision for what the Scripture was intended to mean to its original audience, then it undercuts the whole premise of the debate! And Walton, being a professor at Evangelical flagship university Wheaton College, has the Evangelical bona fides that many will need in order to trust him.
