Beginning Kotlin: Build Applications with Better Code, Productivity, and Performance 1st ed. Edition

This is not a thick book. It has large type and good sized margins. Some will complain about this. Personally I think that makes is easy to make notes in the margins. But the important thing is that, at its core, this book is exactly what it purports to be, a guide to beginning Kotlin.Note it did not say Beginner Kotlin. If you have experience with OOP in any language and are looking to see how the same things are done in Kotlin this is the book for you. Otherwise you should consider another source.
