When schoolchildren break up for their summer holidays at the end of July, India Jago, aged 12, and her brother Peter, 11, will be taking a vacation with a twist.

While their friends jet off to Spain or the Greek islands, the siblings will be hunting for imaginary unicorns in Somerset, southwestern England, while learning about moral philosophy.

The Jagos, from Basingstoke, Hampshire, are among 24 children who will be taking part in Britain's first summer camp for atheists.

The five-day retreat is being subsidized by Richard Dawkins, the evolutionary biologist and author of "The God Delusion," and is intended to provide an alternative to faith-based summer camps normally run by the Scouts and Christian groups.

Crispian Jago, an IT consultant, is hoping the experience will enrich his two children.

"I'm very keen on not indoctrinating them with religion or creeds," he said earlier this month. "I would rather equip them with the tools to learn how to think, not what to think."
