Description du livre
Colt's mother has now joined the Lost World Circus to become their new vet and keep the animal's vaccinations up to date and hopefully the dreaded DORF at bay. As Colt gets used to life in the circus, living in a caravan and discovering all the amazing animals he's never seen or heard of before, one night he uncovers a mystery. Caruso the gibbon, miserable at being kept in his cage, has found a way to cleverly escape at night to nearby trees, returning by daylight. When Caruso doesn't return one morning, it's a race to see who can find him first, Colt or DORF? With the unlikely help of the circus handyman, Colt comes up with a plan to rescue Caruso and give him the freedom he craves by investigating the stories told about the mysterious island of Skull's Jaw.
