Dogs are disappearing in her neighborhood, and Maggie Brooklyn Sinclair knows all about it. After all, she has a semi-secret after-school gig as a professional (ok, amateur) dog-walker.

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

My love of reading started when i was young, and it gives me immense pleasure to provide books to Spread the Word Nevada, an organization that passes them on to children in the community. They are a terrific organization supporting an important cause. If your local I encourage you to check them out. For those living further a field, look in your own community, their may already be a similar program in place. And if not, you can always help start one.

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. ...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, ...more

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 ...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 ...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 ...more

This book is about a girl named Maggie and she is concerned why dogs are disappearing in Park Slope and she wants to know what is going on. She is also doing a bunch of things that people aren't realizing, also she has thus after school program where you have to walk dogs, basically a (dog walker). But the bad part about all of this is that she has to help her enemy well ex-best friend Ivy find her missing dog.

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 ...more

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.

Fun girls' mystery novel. I enjoyed the story idea, okay the solution was pretty obvious, but I could overlook that. I lost one star because of all the dating talk for 11-12yr olds. I would find crushes and budding relationships believable, but getting advice on datable locations from your twin brother? And parents aren't consulted before heading out to a movie theatre with your date? But great mystery and cute dogs too. It's a winner, I'll be reading the next in the series.

This book is one of my favorite books! I enjoyed this book A LOT! It is mainly about a girl who solves dog mysteries. If you like books that talk about mystery, life, and friends, be sure to read this AWESOME book! This book is a long and thick book, but I understand the book. The topics were interesting, and I could picture every page's details. This book is probably good for 4th graders and up. I think that everyone should read this book, because it is VERY good, and I am not kidding!

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 :)

A savvy, sweet middle schooler has a dog walking job after school that brings extra cash, friendships and mystery. Set in uber-hip Park Slope, with wonderfully realistic great characters (crushes, ex-BFFs, quirky only-in New Yorkers), the puzzle of who is behind a series of dog-nappings makes a fun read. The ending's a bit tidy and silly, but I doubt any girl would mind!
Cute, nice, not the best book I've ever read, but enjoyable enough for tween readers. Probably too simple for YA. You can see the mystery and the solution coming a mile away, but the characters are well-drawn for the most part and the whole losing-your-best-friend-in-fifth-grade thing is spot on. I'm thinking precocious 4th graders.

The author does an excellent job in this book of pulling the reader in. I really enjoyed reading it and wanted to read more when I was done. There is humore and problem solving as well as pre-teen situations. I think middle readers will enjoy the mystery and fun of this story.

This wholesome speed read will be highly appealing to tween girls, especially those who are fond of dogs and mysteries. Maggie Brooklyn is an endearing character, with typical tween girl issues like crushes and friendship troubles. New York City is a fun backdrop for this amusing mystery... (click for full review

pretty cute kid mystery set in park slope. although some aspects of the resolution felt a little unlikely to me, it was not to the point that i will strenuously object. especially because i really like the portrayal of the relationships betwixt the characters. also, i feared it was going to be a little to twee and hipster, so was glad when that fear was (mostly) unfounded.

This is the first Maggie Brooklyn mystery that I have read. Maggie is a dog walker in Brooklyn. She lives in a brownstone with several other families. Dogs from her neighborhood keep disappearing and her ex best friend needs her help recovering her dog. Maggie makes lots of astute observations and solves the mystery!

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. :)
It's so good. I actually tried to name my name Maggie Brooklyn, no kidding. Obviously I have to get used to it because it's one of my New Years resolution of the many. And Leslie margolis makes it sound so weird how she thinks milo is the best leaner in Brooklyn. And the ivy/Kermit problem and Brenda/dr Reese thing. And

I loved Maggie, the dog walker. Bit by bit, she pieces together the puzzle of the missing dogs. Along the way she deals with her crush Milo, a former best friend and her twin brother Finn. Calling all girl mystery fans, I think you will enjoy this one. Hopefully there will be other mysteries to solve.
