Today I started and read (yeah, I am a fast reader) Joseph M. Spencer's new book, The Vision of All: Twenty-Five Lectures on Isaiah in Nephi's Record (Salt Lake City: Greg Kofford Books, 2016). I would highly recommend it, as it is full of interesting insights. Furthermore, it is very accessible, so you don't have, say, know biblical Hebrew or contemporary BOM or Isaiah scholarship, so it is a volume I will probably loan out to friends with questions about Isaiah in the Book of Mormon.
Spencer also wrote another wonderful book, An Other Testament: On Typology. I do look forward to future volumes from Spencer.
