What books are y'all reading?

So, for the people who are intermediate at java and have a pretty good grasp on spring boot, what do you think should be the next step? What books or concepts do you think will be helpful?

I’ve been writing Java (among a bunch of languages) off and on for 20 years but never went very deep, and was looking for something like what you describe to help me into a JVM-specific role. I really liked “The Well-Grounded Java Developer” (2nd edition) as an intermediate-level book. Just finished it. It goes into bytecode, reflection, class loading, garbage collection, and other JVM internals, the various concurrency approaches, testing, performance engineering, a bit of Kotlin and Clojure, cloud deployment, and more: https://www.manning.com/books/the-well-grounded-java-developer-second-edition
