The topics were hit or miss for me. The early chapters, about why you would write a technical report, were a bit dull. I thought the chapters in the middle of the book were great, especially the ones on Technical Writing Style and color theory. The chapters at the end were far too specific in application to keep my attention. I would give it three stars if it weren't for the fact that I find my self referencing the mid chapters quite a bit since I finished reading this book.
