Emily loves the bush and the native animals on her family's reforested property, particularly the beautiful rainbow lorikeets that nest in one of the tallest trees. But then her father is diagnosed with a terminal illness, and Emily's world enters a tailspin. Her twin brother, Alex, refuses to accept the truth. His coping mechanism is to build elaborate additions to his treehouse in the superstitious belief that it will avert disaster - leaving Emily to deal with harsh reality on her own. When Alex secretly adopts a feral kitten, going against everything that's important to Emily, the siblings' emotions reach boiling point - with potentially dangerous consequences for them all.
