The worst series ever. Never buy this book. Book 7, 12, and 16 are the worst. It is a complete rip off of Diary of a Wimpy Kid. At least inside Diary of a Wimpy Kid Greg writes why he calls it a journal, but for Zombie? No. He just crosses out diary and writes journal for no reason in the book. And in book 7, guess what the rest of Zombie’s family does when they find out him, along with his brother, cousin, and friend go missing? THEY HAVE A PARTY. And Zombie says his friends are the best he can have in the world when they kick his head around like a soccer ball, don’t sit with him at lunch, say he’s disgusting because he likes small animals, and laugh at him when he’s embarrassed. WHAT KIND OF FRIENDS ARE THESE?!? And book 12 is a COMPLETE RIP OFF of Pokemon, even the NAMES. HOW UNORIGINAL IS THIS AUTHOR? He even rips off Super Mario in book 16, where there are mushroom houses and pipes poping up everywhere. And MARIO IS MARCO AND LUIGI IS LOOIGI. So NEVER, EVER, BUY THESE BOOKS.
