This was a fun mystery to read about some kids who lose their pets after they dress them up for the 4th of July.
I liked that there was stuff about King George, Thomas Jefferson, and the Declaration of Independence.
I liked that the kids use teamwork to solve the case and they never gave up trying to find their pets.
It was a good story.

I read the original A-Z Mystery stories when I was a little kid and greatly enjoyed them, I had only ever gotten to the Letter T, so I figured this year I would re-read and actually complete the series all this time later, and I was delighted to learn that Ron Roy has continued on the Green Lawn Mysteries and characters, and gone on with Calendar Mysteries and the A-Z Super Mysteries, which I will get to reading later on.

This series of 12 books focuses on the younger relatives of the Main Characters of the original series, and it's charming and fun to see the adventures they all get up to in this fun additional series.

Brian, Bradley, Nate and Lucy all want to be mayor for the day, so they dress their pets up for the 4th of July parade for the best dressed pet. But, their pets have other ideas. Will the kids find their pets in time for the contest? Where could they have run off to?

This series is nor as in depth as the WaS mysteries but, we are still enjoying them. Two more to go.

Bradley, Brian, Nate, and Lucy decide to dress up their pet pony and dog to try to win a 4th of July contest to be mayor for a day. Unfortunately, their pets aren't on board with the plan and the kids have to find out what has happened to the animals. A great early reader mystery that can keep an early reader intrigued. This is a fun series.

I think everyone has lost a pet and that’s what happens to the kids in this mystery. Animals can be pretty tricky sometimes. I like how the author captures the stress of looking and the joy and relief of finding.

This is another fun mystery in the Calendar Mysteries series by Ron Roy. We tore through the A to Z Mysteries by the same author and now we are patiently waiting for each month in this series to get published. This new series is for younger children, so it's perfect for our girls right now, but they might grow out of the stories before the series is completed. No matter. We've had fun with them and the characters and setting are familiar to us by now.

This story was fun (and quite predictable.) I like that these mysteries are simple, harmless, and understandable for young children. There is no danger, menace or unsupervised children putting themselves into a harmful situation. And I love the interaction between the younger children and our old friends: Dink, Josh, and Ruth Rose.

I liked this passage. It is important not to give up. They didn't give up, and went to the police to ask for a help.

I'm not good at reading mysteries. However,it was not so difficult for me to read this book. I could understand the story. I'm happy.

I liked Calendar Mysteries until we blazed through all 26 A-Z Mysteries last year, and now I feel like these aren't that interesting or even much of a mystery. I read it aloud to my 7 year old, and he liked it, though. We'll probably finish the series.

Update: Listened in the car together with the four youngest.

I just love these cute little stories. They've become a guilty pleasure of mine. I know they're meant for young children but they are really fun. This one has a great quote in it when the kids are deciding what part of the mayor they want to be. I even had to read it to many husband 😸 Another good book in the series.

My 7 year old read a little of the way into this and decided it was too scary for her just yet. We will check these out again at a later time.
