This book is in Spanish, and if you don't know the rules of Nurikabe and cannot read Spanish, then you will be disappointed. However, if you are willing to go to[...], try a few Nurikabe puzzles, and learn the rules, then you will find this is an inexpensive way to obtain a book of engrossing and pleasurable puzzles.
Nurikabe is one of my favorite Japanese logic puzzles--a puzzle I return to often. Having become bored with Sudoku (I find them more tedious than fun these days), my current rotation of puzzles includes Masyu, Nurikabe, and Kakuro.
The Nikoli line of puzzles cannot be matched for their quality. Like their other books, this book is of the quality I have come to appreciate from Nikoli. Unlike other puzzle books, their rating system actually works (easy puzzles are truly easy, the difficult puzzles are truly difficult while not impossible).
This particular book has standard paperback binding, which is not ideal for a puzzle book. However, its size is compact enough for a pocket or purse. I personally was able to finish all puzzles before the binding fell apart (a common problem I have with traditionally-bound paperback puzzle books). If you don't like this type of binding, I suggest looking at Nurikabe & Sudoku, which is more expensive and also has fewer puzzles.
Overall, for $2.99 with free shipping through Amazon Prime, this was a good deal for me.
