Over the course of the next strange, strained year, Sunny will refer repeatedly to her previous lives, and how they ended.
Her parents, Lena and Odhran - who rushed headfirst into family life after an accidental pregnancy and a hasty registry office wedding - are left desperate for answers.
Is their child suffering from disassociation, a psychological disorder, or something more? Has she been contaminated by their own haunted histories - by Lena's experiences as an indie musician in the era of sleaze, by a shady legacy of madness in Odhran's family? Can we ever really protect our children? What if we can't?
