If you could bring back just one animal from the past, what would you choose?

It can be anyone or anything from history, from the King of the Dinosaurs, T. rex, to the King of Rock 'n' Roll, Elvis Presley, and beyond.

De-extinction - the ability to bring extinct species back to life - is fast becoming reality. Around the globe, scientists are trying to de-extinct all manner of animals, including the woolly mammoth, the passenger pigeon and a bizarre species of flatulent frog. But de-extinction is more than just bringing back the dead. It's a science that can be used to save species, shape evolution and sculpt the future of life on our planet.

In Bring Back the King, scientist and comedy writer Helen Pilcher goes on a quest to identify the perfect de-extinction candidate. Along the way, she asks if Elvis could be recreated from the DNA inside a pickled wart, investigates whether it's possible to raise a pet dodo, and considers the odds of a 21st century Neanderthal turning heads on public transport.

Pondering the practicalities and the point of de-extinction, Bring Back the King is a witty and wry exploration of what is bound to become one of the hottest topics in conservation - if not in science as a whole - in the years to come. READ THIS BOOK - the King commands it.

Helen Pilcher was a stand-up comedian for more than ten years, before the arrival of children meant she couldn't physically stay awake beyond 9pm. During this time, she performed at the Edinburgh comedy festival, at London's Comedy Store, and at various smoky pubs and clubs across Britain. She was a finalist for Jongleurs New Act of the Year (1998, 1999), the BBC New Stand Up Competition (1999) and Channel 4's So You Think You're Funny (1999). In 2002, she teamed up with fellow comedian Timandra Harkness to write and perform 'The Comedy Research Project' a stand-up comedy show commissioned for the very first Cheltenham Science Festival.

Unusually, Helen is also a professional science writer, with a PhD in stem-cell biology. She was formerly a journalist for Nature online, specialising in genetics; before that, she ran the Science in Society programme at the Royal Society, and before that, she worked as a senior scientist for a biotechnology company, engineering a series of human stem cell lines for transplantation into damaged human brains, this following on from her doctoral research into stem-cell therapy for Alzheimer's disease.
