Fourteen-year-old Dylan is sent to live with his estranged grandfather, Angus. Basically strangers, the two avoid each other as best they can. One day Dylan discovers a young orca stranded high up on the rocky beach. Dylan runs to tell his grandfather. There’s nothing that can be done, says Angus. The sun is coming up, and soon the orca will die of exposure. But Dylan knows he has to try to save the whale. He collects towels to cover the delicate skin of the orca and begins transporting buckets of water from the ocean below to keep it hydrated. It’s grueling work, and it will be hours before the tide comes back in and the water is high enough for the orca to swim free. Angus is moved by his grandson’s determination and helps as best he can. They both desperately hope that soon the orca will be able to join its family, who have been calling out to it just offshore.
After a hang glider crashes into the pool of the house where Dinah and Madge are house-sitting, the hapless pilot creates more than a splash of suspicion in Dinah's mind. Why does this itchy intruder make off with Dinah's inflatable turtle? Why is someone trying to drive their cat-mad neighbor away? And what is the connection with the balding stranger seen lurking behind the hedge? And when Madge's boyfriend starts a campaign to save the endangered spotted owl, it seems that a crooked politician may be out to destroy the habitat of the near-extinct animal. While Madge paints, Dinah brushes aside suggestions that she be a quiet, well-behaved guest in this posh North Vancouver neighborhood. There's just too much for Dinah and her friends—tree-fanatic Pantelli and irritatingly conscientious Talbot—to investigate in this hilariously suspenseful adventure. Along with learning about endangered animals and fragile ecosystems, Dinah runs across clueless reporters and greedy developers, all the while continuing to belt out her favorite songs and satisfy her healthy appetite.
