Query: Great for fans of word search puzzles, hard for the rest

In general, I found the word puzzles in this book to be very hard. Most of them are in the category called "Scramblegrams." The structure of these problems is that a series of words are scrambled, with the letters above a series of dashes to be filled in. Some of the letter positions are highlighted and those letters will then be used to create a final phrase. Another type of problem is the "word melt", where you start with a word and change one letter at a time to end with another word. Each intermediate step must also be a valid word. There are also a few "word search" puzzles.In general, I am not a fan of word puzzles; I do them on occasion for a change a pace and challenge. In this case, for me, the emphasis is on challenge.
