After their parents disappear, sisters Sabrina and Daphne Grimm are sent to live with their grandmother, Relda Grimm in the town of Ferryport Landing. As soon as the sisters arrive, they learn they are descendants of the Brothers Grimm, who were actually detectives of the magical phenomenon perpetrated by the Everafters, a parallel race of magical beings. They soon discover it is the Grimm family's legacy to keep the Everafters in line and the two sisters are the sole heirs to this challenge. Working as detectives in their family business, the sisters Grimm solve mysteries possibly connected to the disappearance of their parents. While following their family traditions, they also must deal with Puck, a trickster fairy boy who lives with them. Unfortunately for the sisters, the Scarlet Hand, an evil group of Everafters, seeks to escape from the town and take over the world.

When Mr. Grumpner is murdered in a particularly unusual way, it is up to the Grimms to find the Everafter who did it. A great friend turns into a great enemy, and when the school is blown up by Rumpelstiltskin, who turns into a human bomb, Mr. Canis doesn't make it out in time.
• The Problem Child: The Sisters Grimm face their parents' kidnappers, an organization of Everafters who call themselves the Scarlet Hand. One of them turns out to be Little Red Riding Hood, and the other, the Jabberwocky, an unstoppable killing machine. The girls have little hope of rescuing their mother and father until their long-lost Uncle Jake returns home with stories of a weapon, now missing, that can kill the Jabberwocky. Sabrina, given a wand by Uncle Jake, gets a magic addiction. Only the Blue Fairy can put the pieces of the Vorpal Blade together.

Puss in Boots (now an exterminator), Cinderella (a radio relationship counselor), Briar Rose (owner of a coffee shop), and their old enemy, Prince Charming, are among the many suspects. The girls get sucked into the future and are surprised at what they see.
• Tales from the Hood: A kangaroo court of Everafters, led by the Queen of Hearts, is determined to find Mr. Canis guilty and force the Grimms out of Ferryport Landing.

• The Inside Story: Picking up where the cliffhanger ending of book seven left off, this book follows Sabrina, Daphne, and Puck through the Book of Everafter, where all the fairy tales are stored and enchanted characters can change their destinies. The girls and Puck must chase the Master through a series of stories. Soon, however, they are confronted by The Editor - the book's guardian - who, along with an army of tiny monsters known as Revisers, threaten the children with dire consequences if they don't stick to the stories. They move from one legendary tale to the next doing their best to find the Master and stop his plan to steal and inhabit the child's body.
• The Council of Mirrors: The final battle has begun. Sabrina, Daphne and their family and friends must fight the Master, who has failed to escape Ferryport Landing.
