Flying Blind

In Flying Blind, musical 15-year-old Essie is missing her dad; her friend at school is treating her strangely and a new boy with an army of siblings moves into their coastal town from the Outback.
If this isn't enough to deal with, a junior lifesaver sweeps her out of the sea when she's hightailing it to the shore after sighting a fin. It was a dolphin after all, so she wasn't really in trouble. Does that mean he likes her?
Sometimes searching for significance and trying to fit in will lead to blind loyalties before we can recognise our true friends.
