The distinctive white-tailed sea eagle was driven to extinction in Britain more than 200 years ago, but this immense predator is making a return to our skies, thanks to Roy Dennis, an ornithologist, conservationist and arguably the driving force behind the UK's reintroduction agenda.

Roy was instrumental in returning the Osprey, red kite and golden eagle to the British Isles, but the road to reintroduction isn't an easy one. In what will surely be the seminal book on British reintroductions, Roy details the painstaking process of returning the Goldeneye to Scotland, one duckling at a time, the die-hard determination needed to make a dazzling success of the red kite reintroduction and the leap of faith we will all need to make to accept sharing our forests and skies with large carnivores again. He also illustrates all that we have to gain by restoring our ecosystems to balance.

Filled with a lifetime's worth of stories from the front lines of conservation, Reintroduction offers an eye-opening insight into the complexities of reintroducing extinct animals to Britain. It's also an intimate portrait of these apex predators and a reminder of why we need them.
