"Take your cookies elsewhere." That's what the note said in neat, block-like print, attached to a box of Girl Scout Cookies. Someone is out to sabotage the new sweet shop in the neighborhood, and Maggie Brooklyn is on the case. If only she weren't so freaked out herself lately. Maggie's new dogsitting gig has her and her twin brother Finn hanging out in what they fear may be a real haunted mansion. And it's hard to solve real life mysteries when you think you're seeing ghosts!

Coming September 10, 2013!

But just when Maggie's life is feeling like a romantic comedy, Seth disappears! Everyone thinks he's been kidnapped, but Maggie knows better. . . .

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.

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.
