Query: terrible for independent study

Though this book does present all the necessary information for learning about abnormal psychology, it's the dryest, most aesthetically difficult to read textbook... especially if you happen to be studying the material online/through independent study. The publisher needs to redesign the book and/or you need to have a better online course professor. It feels nearly impossible to be interested in this material (which is interesting in itself) if you have to read the textbook front to back on your own without any instruction.
