Lily's epilepsy means she's used to seeing the world in terms of angles - you look at every surface, you weigh up every corner, and you think of your head slamming into it - but what would she be like without her sharp edges?

Prickly, spiky, up-front honest and down-to-earth practical, Lily is thirty, and life's not easy but she gets by. Needing no-one and asking for nothing, it's just her and her epilepsy: her constant companion.

But then Lily's long-estranged mother dies, and Lily is drawn back into a world she thought she'd left behind. Forced to renegotiate the boundaries of her life, she realises she has a lot to learn - about relationships, about the past, and about herself - and some difficult decisions ahead of her.
