Warning: this book contains inventions not yet available to the general public, a fair amount of peril and a ridiculous dog called Cassie.
Introducing the Templeton twins: 12-year-olds John and Abigail. They live with their eccentric father, the renowned Professor Elton Templeton, who has lots of ideas for many things and a past enemy long forgotten, but who is about to burst dramatically into their quiet lives. John and Abigail Templeton learn very quickly what it's like to be faced with difficult choices, but with the help of each other and their knowledge of playing the drums and solving puzzles they embark on an adventure that will pit them against another set of twins - evil Dean D Dean and Dan D Dean. Think twice about messing with this head strong family.
As light-hearted as this tale is, it still touches on serious issues like the loss of a parent and the upheaval that creates. The tone is light and the narrator breaks off from the story now and again to explain various elements of the plot. Puzzles and diagrams break up the narrative, which adds to the playfulness and encourages interaction with the reader. The language is amusing, with various witty acronyms adding to the flavour of the book, and when needed there was enough tension and pace that was easily controlled by the narrator. The Templeton Twins Have An Idea is fun and engaging to read, led by strong characters and a humorous narrator that gives this book an unique voice.
