This is an incredibly helpful topic to write a short, dedicated book to. The author provides an encouraging intro and does a good job painting a picture of why the subjunctive is so vital to learning Spanish. But the grammar explanations are so technical and dense, it quickly becomes difficult and not-at-all-entertaining to try to stay with his explanations. The book itself represents why much of the dry lessons we took in high school and college didn't stick. There are no pictures, no graphs or charts, no visual creativity to help us remember, no stories, no articles, etc. All the exercises at the end of the chapters are fill-in-the-blank or multiple choice. No crossword puzzles, no online games, no drawing, no comic strip completions, etc. The exercises are useful up to a point, so I might continue by doing those first and referencing the chapter if need be. The book and chapters are short, so that might help me keep going. And I'll keep looking - so far it seems like there's a huge lack of fun and creative language learning resources in print and online sources. Feel free to let me know of anything you've found to the contrary : )
