In HN tradition where we all recommend every book we've ever read similar to the submitted one (and Land of Lisp is worth reading), an overlooked recently published booklet I found is Common Lisp in the Wild: https://www.darkchestnut.com/book-common-lisp-application-de... Common Lisp is so flexible in letting you develop the way you want to develop, but if you're a professional programmer looking for a Maven-esque template of "structure your project in this familiar way without sacrificing any of the interactive Lisp dev experience, enumerate version-pinned dependencies, one-step make to build, test, run, deploy the final artifact" like I was that book's suggestions are worth the entry fee and you're left with a stable foundation to deviate from.
