Shipped halfway around the world to spend the summer with her mom’s eccentric Australian relatives, middle schooler and passionate violinist Louisa is prepared to be resentful. But life at the family’s remote camp in the Tasmanian rainforest is intriguing, to say the least. There are pig-footed bandicoots, scary spiders, weird noises and odors in the night, and a quirky boy named Colin who cooks the most amazing meals. Not the least strange is her Uncle Ruff, with his unusual pet and veiled hints about something named Convict Rock. Finally, Louisa learns the truth: Convict Rock is a sanctuary established by her great-grandmother Eleanor―a sanctuary for Tasmanian tigers, Australia’s huge marsupials that were famously hunted into extinction almost a hundred years ago. Or so the world believes. Hidden in the rainforest at Convict Rock, one tiger remains. But now the sanctuary is threatened by a mining operation, and the last Tasmanian tiger must be lured deeper into the forest. The problem is, not since her great-grandmother has a member of the family been able to earn the shy tigers’ trust. As the summer progresses, Louisa forges unexpected connections with Colin, with the forest, and―through Eleanor’s journal―with her great-grandmother. She begins to suspect the key to saving the tiger is her very own music. But will her plan work? Or will the enigmatic Tasmanian tiger disappear once again, this time forever?
