I have endured a great many language learning courses and suffered through several dreadful textbooks that were meant to help, but were foiled by poor layout, missing elements, or less-than-ideal organization. I was pleasantly surprised by this book, however.
I took a summer course with Celia Brickman in reading French for academia and this, naturally, was her textbook of choice. I'm sure that having the author as an instructor increased my appreciation for this volume, but honestly, compared with other volumes I've surveyed, this is clearly superior, with cogent explanations, many helpful exercises, a logical organization, and (important to me) a visually pleasant layout.
