Query: One of the most boring textbooks on the planet

The authors (Lee Galda, et al) of this textbook took a truly exciting and important subject, which I am extremely interested in, and produced the most tedious, lackluster, monotonous, yet overly expensive volume I have ever been REQUIRED to purchase. They should be ashamed for having made sharing the love of reading with children such a mind-numbing experience for future educators. Indeed, there are not enough synonyms in the English language to convey how dull this book is. Do not purchase it unless you absolutely must, and by all means get is a cheaply as possible.
