THE MAGGIE BROOKLYN SERIES

Girl's Best Friend: A Maggie Brooklyn Mystery by Leslie Margolis

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. Maggie hates to see a pup in trouble, so she’s even willing to help her ex-best friend Ivy recover her rescue-dog, Kermit. Kermit’s being held for ransom, and Maggie has noticed some suspicious behavior lately. But she never suspected her crush Milo could be involved…

Leslie Margolis’s pitch-perfect voice and rich characters have endeared her to tweens, and her fans will flock to this hip new series featuring a clever and lovable new heroine, Maggie Brooklyn.

Reviews for Girl's Best Friend

 “This is my kind of book! The mystery starts on page one. Then it’s surprise after surprise, with lots of twists and turns—and chilling suspense.”
• R. L. Stine, best-selling author of the Goosebumps series

“Maggie is a friendly and thoughtful narrator with a sharply logical mind; readers will appreciate her intellect and bravery, and applaud her success.”
• Publishers Weekly

“Set in a recognizable Brooklyn neighborhood, Girl’s Best Friend clips the reader onto a touching, funny story-leash that twists and turns; dogs, their humans, twins of all ages, old friends and even apartments are not what they seem at first. At least, not always… Margolis leaves you wanting to look twice at every familiar gesture and setting.”
• Blue Balliett, award-winning author of Chasing Vermeer and The Calder Game

“Maggie is a smart and competent heroine whose personal life is just as interesting as her detective work.”
• Kirkus Reviews

“Maggie Brooklyn is a smart, funny, capable detective, and a real kid. Sequel, please.”
• Adam Rex, best-selling author of Fat Vampire and The True Meaning of Smekday

“…While the well-crafted mysteries are foremost, it’s the relatable, witty protagonist that makes this novel stand out…. When this dog walker turned detective returns, she’ll be welcome.”
• The Horn Book

“What better cover for a detective than a neighborhood dog-walker? Especially when the case that needs cracking involves missing pets. Leslie Margolis has found the perfect mix—a city story, a tween story, and a mystery that truly keeps you guessing.”
• Gordon Korman, best-selling author of The 39 Clues: The Emperor’s Code and Framed
