'It’s a hot summer’s day in Sydney Town, and nine-year-old cousins Charlie Smith and Rupert Swallow can’t wait to dive into the surf at Bondi Beach. But the beach can be a dangerous place. Out past the breakers, where the seagulls swoop and soar, lurks a strong rip that can drag unsuspecting swimmers out to sea. Travel back in time to January 1907, and join Charlie and Rupert on a true-life, heart-stopping seaside adventure.'
