I love mysteries. I like to pick up on clues, look for a motive, and consider different suspects. In Girl’s Best Friend, Leslie Margolis has the formula for a well-written mystery down pat. She drops subtle clues, includes foreshadowing, and leaves just enough up to the reader’s own imagination.

Maggie has all of the qualities of a great detective. She is smart, cunning, sneaky, and creative. I liked that Maggie was open minded to all sorts of scenarios that would explain who was stealing all the

As posted on Outside of a Dog

Mysteries, in general, have never been my thing. I read a little Agatha Christie, a little Encyclopedia Brown, and of course Nancy Drew, but the search for hidden clues was never as interesting to me as hidden Easter eggs (the real kind, not the DVD variety). I have had kids come to me asking for a good mystery, and for a long time, I had a very short reference list. The aforementioned Mr. Brown, “The Westing Game”, and for fun, Geronimo Stilton. But things have chan

if you have ever read girl detective this is one of the books for you, just reading the back makes you want to read it. but might not be good for very passionate dog lovers XD kidding the dogs are safe...

My opinion about Girls Best Friend it is a really mysterious book about dog napping.

My first reason ,why this book is because this girl named Maggie is persistent.Maggie was always dressed in discusses to find the dog napper.Maggie would find evidence.Maggie would do anything that is possible.

Another reason,is she is really good to witness the problem.Maggie wouldn't be Fredrick Flogo Maggie would be Rocky the Rocketeer who does all the work.Maggie would ask people in a suspicious mood question

This is an excellent middle grade mystery. Maggie exudes personality and I really enjoyed her adventure. The quirky Park Slope residents are all nicely imagined and they really add to the story's crackle. The mystery was a bit more layered than expected, and featured a couple of interesting twists that added up to a great read. I look forward to reading the next in this series.

I think that this book was a very interesting and adventurous book. I liked the way the author described the problem, like it was very easy for me to understand the problem. I also liked the way the protagonist, Maggie Brooklyn, who was a dog walker and a detective at the same time, solved the problem step by ne'er have of her best friend's dog. I thought that it was risky for her because if she found the dognapper (the person who kidnaps dogs), then that dognapper might try to take the dog that ...more

This is a sweet story about a girl who's a dog walker and solves mysteries while doing it. It's marketed to Nancy Drew fans; I'm not entirely convinced about that comparison but it will appeal to girls who enjoy a bit of a puzzle and some unique characters along with their realistic fiction.

SLJ did a great review so I'm including it here for plot point reference--

Shelves: juvenile-mystery
Readers of juvenile mysteries, take note: Maggie Brooklyn is going to be giving Nancy Drew a run for her girl-detective crown. Margolis does a great job of making Maggie completely real - very much an "everygirl" that most kids will relate to very easily. She also makes Maggie's Park Slope neighborhood in Brooklyn come alive.
During the course of the book, Maggie comes up against several very strange things in her accidental profession as dog walker. It's up to her to figure out if the strange th
Oct 31, 2015 Brooklyn rated it it was amazing
Girl's Best Friend has many twists and turn that are in expected. You can never know who the villain is because Leslie Margolis keeps you guessing and guessing. Although the mystery is about dogs disappearing, there are much more mysteries added. This is an amazing book! Who is kidnapping the dogs? Is it Milo, Maggie's crush? Or is it something else... someone else? Read the clues carefully and you'll find out.

I started this precious book today and just couldn't put it down. I love this book. Another series to add to my list!

Maggie is a gem of a little girl! She walks dogs, figures out mysteries and saves the day for dogs and their families.

It's a very refreshing mystery with a child as the detective. I just love it!!!!

Keep them coming :)

Can I give it 3.5 stars? Middle-schooler Maggie Brooklyn lives in Park Slope, Brooklyn, and she has a lot going on. She takes kung fu and art classes, but also runs a secret dogwalking business. Secret from her parents, that is. When Maggie's twin brother, Finn, gets roped into inviting Maggie's ex-best friend, Ivy, to their joint birthday party, the mystery begins. Maggie catches Ivy stealing her dogsitting money, only to discover that Ivy's dog, Kermit, was being ransomed by a dognapper. Maggi ...more

I didn't enjoy this book very much. In my opinion, it focused much more on Maggie's problems, rather than the mystery. It was only toward the end in which I actually felt like she was thinking about how to solve the dognapping, instead of just reading Nancy Drew. There are still some problems. 1. She likes Milo but is always to shy to say much of anything. And that's alright, but then she starts putting herself down: 'Oh, I not special. He wouldn't like me. He probably prefers Ivy. Blah, blah, b ...more

I enjoyed the book,
Maggie is just your average mystery solving dog loving girl. She walks dogs to earn money and when they start to go missing she is up to the task of recovering them.

I loved the book even though it was a bit, no a lot cheesy.

Cute story. Good for upper middle grades. I did let my 4th-grader read it, though, and made sure we talked about some of my issues with the book, namely dishonesty and safety precautions.

I thought this was a a well written book with a few cons. It didn't start out as interesting but it improved as I got farther into the book. Well done Margolis, and to all those readers out there who are maybe interested I hope you find it as fun to read as I did. :)

This book is super cute. I've really started to fall in love with middle grade mysteries. The mystery starts right at the beginning and kept me guessing. I really didn't know who the crook was until the end. There are several mysteries all wrapped up together and happening at the same time. This would be confusing, but the author does a great job of keeping everything straight. Plus, it gives the story a little extra something because you have to figure out which mystery each clue is relevant to ...more

Maggie Brooklyn Sinclair has an ex-best friend called Ivy. She likes a boy called Milo and she walks a dog called Milo. This book talks about mystery and love. When I first read the blurb I found it really weird when I found out that dogs are disappearing. Who would want to catch dogs? I thought it was really nice how Maggie decided to help find her ex-best friend, Ivy's dog even though they're not friends anymore. I hope at the end of the book Ivy and Maggie will become best friends again. I wo ...more

This was a very surprising book. I had originally thought that it would be a bit flat and boring, but it turned out to be just the opposite! There were some great characters, although I would loved some more insight on what really happened with Maggie and Ivy's friendship. I enjoyed the slight crush on Milo, it was a good addition to the book, without taking away from the plot. The mystery wasn't overly complex, but it was pretty fast-paced, and it had a good climax. All in all I give it a 4 sta ...more

A mystery that will make people never want to stop, with smaller mysteries mixed in.
This book was really, really, really awesome! one of THE best books I've EVER read! The author, Leslie Margolis was able to blend the story together perfectly! I loved how it was from a (not completely) perfect girl's point of view, It was able to include mystery while adding the perfect amount of suspense not too short, but not dragging it on for way too long like some other books I've read. It had a good story line/ concept and an interesting ending. As a fellow tween, I'd recommend this to an ...more
