Rosie is mad about the tv series 'Yr Estronos' and about astronauts, and when a spaceship lands in her back garden, she cannot believe her luck. This is a novel about friendship, about time-travelling, about growing up in a complex and difficult world, and about pushing the boundaries of the imagination to the extreme.

From her stunning debut novel tu ôl i’r awyr (behind the sky) – winner of the 2021 Wales Book of the Year – Megan Angharad Hunter has established herself as an author whose sharp sensitivity captures and celebrates the voices of people too often left on the margins. Often focussing on themes of mental health, disability, and sexuality, she is a new and vital voice in young adult fiction. Her second novel, Cat, was published as a contribution to the prize-winning Y Pump (The Five), a collaborative series of writing for young readers.
