In Low Tide, a science fiction adventure, Charlie
Snelling and his friend Wiremu go out to sea so they can fish. The tide is unusually low and when they start looking around, Charlie's little sister, Elisabeth, is found tagging along behind them. They spot a ship up on a tall rock and decide to explore it. They see a name on a bell but can only make out the letters A and L. They figure it's the Alexander, which divers are searching for because it holds treasure. They are very excited until everything starts rumbling.
A huge tidal wave carries them and the ship up into the Knuckle, a cluster of mountains, where the Koroua, a crazy mountain man, supposedly lives. Charlie, Wiremu, and Elisabeth lie still on the ship too hurt to move. Charlie hears something climbing aboard and then he sees it. Standing before him is the Koroua, with black teeth and white hair all over its body. All they wanted to do was go fishing, but soon, all Charlie wants to do is take the ship with the treasure and make it home alive. I liked how there was one problem after the other. William Mayne's writing is descriptive and very creative. The beginning, middle, and end all have adventures of their own and are nothing alike. I'm glad I kept reading it because the end was really surprising. I would have never expected it!
