Martin Hughes-Games focuses his attention on the precarious fate of animals that have evolved on islands: when disaster strikes, there is nowhere to run. The Tasmanian devil is threatened by a disease which has wiped out 80 per cent of the wild population. It could be extinct in a decade so scientists are searching for a cure and zoos are desperately trying to breed them. The rare Mauritius kestrel has been saved from extinction, thanks to Carl Jones. The wild population was once down to four but over 10 years Carl has bred the species back from the brink. The beautiful Aye Aye faces a double threat; not only is its Madagascan habitat being destroyed, but it is seen by some locals as an ill omen and so is killed on sight. Martin follows the story of tiny Styx, whose life hangs in the balance.
