"Killer Energy" will be the 23rd Horrible Science title and brings together a number of strong science themes - heat and cold, nuclear power, recycling and how the human body powers itself - making this is an excellent classroom book as well as a popular playground read.

There are the usual gory details, such as why going to the loo in space can freeze your pee and which liguid chemical is used to preserve pets.

Plus you can find out how your body turns stodgy school dinners into energy, why steaming manure can warm you up and how to build your own geothermal power station.

With strikingly different cover and a mass of information, "Killer Energy" proves that Horrible Science still has a lot of powerful material for turning young stomachs.
