I'm looking for a guidebook or some other companion to Heidegger's "Being and Time". Ideally, I'd like to find a book that steps through the entire original work, providing summary and background to better understand Heidegger's more technical points throughout this work (no small task, I understand). A little about me - I have a BA in philosophy and quit a MA in the subject to move to computer science, and most of my philosophical background is in the analytic tradition.
One possibility I've found is here: https://www.amazon.com/Guide-Heideggers-Contemporary-Continental-Philosophy/dp/0791448002
Is this a decent guidebook? Are there any other recommendations? Thanks.
