The Phoenix Project is a fiction novel about an IT department for a large car company that experiences management dysfunction and battles frequent technical debt, but ultimately overcomes it by adopting the best practices of DevOps. I first read its non-fiction companion book, the DevOps Handbook, which got me drinking the Kool-Aid, but this is also a wonderful, breezy read (no small feat for such a technical topic)…
I think I wouldn't unequivocally recommend it because it could be hit or miss, so a bad choice for "one book only", but overall: yes, worth reading.
