A Door Near Here, by Heather Quarles

When Mom gets sick (drinking bottles of vodka after bottles of vodka) and no longer takes care of the kids, eldest daughter Katherine tries to take charge and protect her three siblings. But she must struggle with a nosy teacher and the foibles of her brother and two sisters, the youngest of which is convinced that she can find the door to Narnia and get help from the great lion Aslan.

I am so tired of reading YA books about alcholic parents who let their children fend for themselves and the terribly dreary disintegration of life as these kids attempt to manage on their own. It becomes the same tired exercise as the author cooks up one crisis after another as life gets worse and worse. In this case, half of the crises end up just being non-events (in one case, the youngest disappears in a grocery store - presumably lost - then suddenly reappears as if the author forgot her own story -- continuity, anyone??). *sigh* Perhaps I would have enjoyed this book if it had been the first child-abandonment piece I had read. But it wasn't and I'm tired of them...
