Inhalt: Two of Australia's most acclaimed and high profile writers co-author a sensitive and ultimately hopeful story about our growing climate crisis. Nyx lives in the Tasmania of 2091 – deforested, over-mined and affected by bushfires and drought. With sea-levels rising, Tasmania is marooned and abandoned to its fate. Nyx's widowed father wants them to leave while they can, but for Nyx, West Hobart is all she has ever known, and where her mother is buried. She finds solace in the single living tree on the dusty reserve near her home, an 80-foot pine that has defied odds and survived the climate crisis. Bea lives in present, beautiful, Tasmania and is facing a move to the mainland. She will miss the giant tree that she climbs to seek solace from bullies. One day she leaves a despairing note, the words pouring out her troubles, stuffed in a hole in its trunk. Nyx finds the note, and writes back. The girls begin a correspondence across two different time periods and they form a friendship that defies the logic of time. When Nyx faces life threatening fire and then floods, she must turn to her friend Bea to change the future.
