Shortlisted for the CILIP Carnegie Medal 2016, this mesmerising and mysterious novel by Printz Award-winning author Marcus Sedgwick is written in four cleverly interlinked parts and can be read in 24 different ways. Spanning thousands of years, The Ghosts of Heaven can tell us a secret as old as time, about survival, discovery, and the effect of the spiral - a symbol that has no end - on all our lives.

It's there when a girl walks through the forest, the moist green air clinging to her skin. There centuries later in a pleasant green dale, hiding the treacherous waters of Golden Beck that take Anna, who they call a witch. There on the other side of the world, where a mad poet watches the waves and knows the horrors they hide, and far into the future as Keir Bowman realises his destiny. Each takes their next step in life. None will ever go back to the same place. The spiral has existed as long as time has existed. Follow the ways of infinity to discover its meaning.
