The Sister

By Poppy Adams

Ginny has lived alone for years in the falling- down mansion that used to be the biggest, best house in the area. But those days and the money that enabled them are gone for good. An old woman and crippled with arthritis, Ginny has shut most of the house up and sold off its contents. She lives alone.
It wasn't always like that, of course. She had a mother, a father and a younger sister.  The parents are deceased and the sister, Vivi, left decades ago. But now Vivi has sent Ginny a letter informing her that she is moving back home. Why, after decades of estrangement, Vivi is returning home, she doesn't say.
At first Ginny is thrilled her beloved little sister is coming home. But once Vivi is actually home, Ginny finds her presence too disruptive, too unsettling. And when Vivi starts to rehash old history, laying down a few home truths that Ginny refused to or was unable to see, it is intolerable for Ginny.
Ginny obviously has some kind of mental limitation, though precisely what it is isn't explained. Once the sisters are reunited it quickly becomes clear that they view their history together from completely different perspectives. It also becomes clear that no one in Ginny's life, not her parents, not her sister, not her doctor, not her teachers ever told her about her mental limitations. Ginny isn't stupid and she long ago figured out she was different. But she was never given a explanation as to why or any real help coping with it. So when Vivi pushes her way into Ginny's cocoon of solitude, it really upsets Ginny's precarious mental balance.

This was a rather slow story. I skipped over several paragraphs, especially the mothier parts (moths are an interest Ginny shared with her father).  Although it is usually interesting reading about dysfunctional families,  I didn't enjoy the mystery of what exactly Ginny's problem was, which is never made clear to the reader or even to Ginny. At one point, Vivi explains exactly what it is, but Ginny refuses to hear her and, since the story is told from only Ginny's perspective, the reader doesn't get to hear it either. Any way, the ending was pretty predictable. No real surprises there.

Published in the United Kingdom as The Behaviour of Moths.
