I don't usually claim to have really read textbooks from classes I've taken because I generally focus on the lectures and use the textbooks as a reference (and source for homework problems). Unfortunately, I just took a Financial Accounting Principals class in which the professor didn't provide much instruction. Thankfully, this textbook turned out to be a pretty good read (for an accounting text). I read it slowly and carefully, especially at the beginning, and came away with what I feel is a reasonably strong foundation of accounting knowledge. I hadn't taken an accounting class since High School but I've worked in management for most of the last decade. I'm glad I read this book as it gave me a better foundation of financial accounting knowledge.
Though not a page-turner, the authors do a good job of using real-life companies and examples to keep things engaging. Examples are generally provided in an "Excel" format to make them easy to follow to. I'd recommend it overall.
