Hexwood Farm is a bit like human memory; it doesn't reveal its secrects in chronological order. Consequently, whenever Ann enters Hexwood, she cannot guarantee on always ending up in the same place or even at the same time. Hexwood Farm is full of machines that should not be tampered with - and when one is, the aftershock is felt throughout the universe. Only Hume, Ann and Mordion can prevent an apocalypse in their struggle with the deadly Reigners - or are they too being altered by the whims of Hexwood.
