Bottom line, wait for a more competent creator of Nurikabe puzzles to publish a book, and continue to solve the various ones found online.
Good feature: I've done about twelve of the harder puzzles, and many are truly excellent, clever, and thought provoking. Only one so far has had an alternate solution (such errors can creep into most books), and I haven't yet had to use his incorrect rule.
If that rule were corrected (and none of the puzzles needed his old rule for unique solution), I would rate this book 5 stars. I still recommend buying it, but use the rules on the web site I've listed.
I like Nurikabe more than Sudoku, and like "Masyu" even more ([...]).
This author has indeed changed the rules of Nurikabe; he has not stated that he has changed the rules; nor has he explained his own rules very clearly! (I was very confused, until someone in the Usenet newsgroup rec.puzzles explained what the changed rules must be.) That is the main reason why I only give the book 4 stars. I actually prefer the altered rules to the usual ones (established by Nikoli), but that is another story, which I will tell in the longer review.
As I stated in a comment on one of the other reviews:
In fact, all of the puzzles in the book (with the single exception, so far, of puzzle #76, which has two slightly different solutions) have unique solutions, according to the altered rules. Many of these solutions are also unique according to the usual rules, but many of them aren't. (The altered rules, when properly understood, imply the usual rules, but they also impose an extra constraint.)
