This was just ok. It was kind of cute and has a nice message that should resonate with kids, but I expected it to be cuter.
The main issues I had were with the writing and the content, the actual scares. The structure was that this little mouse noticed all of these things which were frightening at first, but upon closer inspection there was always a rational explanation and it turned out to not be scary. I'm not a fan of repetitive writing, but I admit that it would be easy for read-alouds and kids can pick up the thread easily and say the words from memory. It always asked what it could be, and then revealed whatever it was, saying "That's all. Not so scary, after all."
The rhymes were very rudimentary and simple:
"One spooky night when the moon was bright, Mouse crept around, and this is what he found..."
"And they sang, "Trick or treat! Giggle and fright! It's fun to be scared...on Halloween night!"
I thought the giggle and fright was out of place and didn't fit at all. That's not something people say on Halloween at all.
I'm not a fan of onomatopoeia and this was full of it, describing the sounds of the things Mouse was afraid of. I personally wouldn't want to say these words aloud, like "Flit!" and "Eek!"
The scares themselves weren't as Halloween as I would have liked. Every time I flipped the page, I expected it to be something really spooky, and I was disappointed when it wasn't. There were bats, which was the best, a scarecrow, a jack o'lantern, and trick or treaters, but there were leaves, apples, kittens (which would be scary for a mouse!), which weren't that successful for me.
The trick or treaters gave him a piece of candy corn, which he took back to his parents, so that was pretty sweet. He survived his first Halloween and saw what it was all about. The illustrations are full of deep, dark colors and I wish they had been brighter and showed more variation, because things were a little muddled and all the pages had the same color scheme. They were cute though, especially all of the animals and the scarecrow.
