Ryan chats with Rachael Boast at the Edinburgh International Book Festival just before the two of them were due to read. Rachael talks through some of the ideas behind her Forward Best First Collection prize winning Sidereal, discusses her interest in time, why astrology shouldn't really be used to predict things and how writing poetry is like playing a piano with your eyes shut.
