Spellfall is a fantasy novel by English writer Katherine Roberts, published on 19 October 2000 by The Chicken House and aimed at pre-teens.

The story concerns a 12-year-old girl named Natalie who is kidnapped by a wizard named Hawk who needs her to join his spellclave (group of bonded spellmages) to receive the Power of Thirteen and invade Earthaven (an enchanted realm) to get revenge on the Spell Lords that banished him for breaking a treaty.

Julie and Tim left London due to the marriage, so that the family live in an English small town whose name is Millennium Green.

Then Merlin stays in Earthaven to acquaint the Spell Lords with the technology, since a bigger knowledge about computers would help them to understand Oq's system better.

Jo, the most athletic girl in the school, is extremely big, has brown hair dressed like a fringe and possesses, unlike Natalie, very good eyes.

He used to work as a salesman until he lost his job, so that he always stays at home and mainly spends his time cleaning his prestigious car, which he had not been driving any more since the death of Natalie's mother.

As she told her son before marrying Mr Marlins, she regards Natalie as a confused little girl and her father as being an unhappy man.

Tim also detests Natalie and her father, making them responsible for his anger and terrorising his stepsister to get rid of his aggressiveness.

He has made friends with a gang composed of some of his classmates; to enter that group he had to pierce his ear with an earring that looks like a skull.

The majority of reviews were positive, for example the Sunday Times said the novel was "Involving and suspenseful,"[1] and the Voice of Young Advocates "highly recommended" it.

", The Observer who said "A welcome and well-written addition to the sorcery genre,"[1] and the Gary Dalkin, British Science Fiction Association, who said, "...keeps the adventure, twists, turns and thrills coming at a breathless pace.
