When Tom's big brother goes from mostly evil to very evil crazy stuff happens. Like almost killing a goldfish. When Tom and his friend bring the fish back to life with a battery, the goldfish is not just a goldfish. IT'S A ZOMBIE GOLDFISH!!! I have to say i was not sure when i got this from my library because i had seen a review that said this book was a little boring. But when i got into it, it was AMAZING! now this book is kind of two story's in one but with the same topic. So i think you need to try it. You might just like it, I know i did! So? what you waiting for? read it!
