Irene Pereyra: Universal Principles of UX
This book obviously follows the format of Universal Principles of Design, but it is no match to the classics. It focuses on UX, which is great for digital design, but the principles are falling short, especially towards the end. I would say 60 principles are solid and 40 are fillers. The author also pimps many of her own work, which makes it less universal. The book is still worth a quick read through.
