Halloween is a popular seasonal theme for KDP puzzle books, but it is also easy to make a book that feels too generic.

If you start with a broad idea like “Halloween word search book,” you will probably end up using the same common words as everyone else: pumpkin, ghost, witch, candy, spooky, costume, vampire, monster, spider, haunted.

Those words are fine, but they do not give your book a clear angle. A better approach is to niche down first, then create puzzle themes and word lists that fit that specific idea.
