Ruby Redfort: Undercover agent, code-cracker and thirteen-year-old genius - there's nothing average about her. Only this time it is an adventure in the wild, and it will take all Ruby's got just to survive. This time, tigers are roaming the streets of Twinford, and it looks like someone has deliberately released some very rare and very dangerous animals. Things are going to get wild - and Ruby is going to get badly lost in the wilderness.
