Here's a little passage that struck me as being very apt to my own situation: "Everywhere you looked there were books. On sagging shelves, in boxes, having in bags from the ceiling, propping up the table and stacked up in such precariously high piles that they threatened to collapse at any moment" (Magyk, 21). Things here aren't quite that bad, but we definitely have the same book hoarding problem as the Heaps.
I also read the first three Shopaholic books: Confessions of a Shopaholic, Shopaholic takes Manhattan, and Shopaholic Ties the Knot.
In any case I finally got around to reading the first few books in the series. They were OK. I actually liked Shopaholic takes Manhattan better than Confessions of a Shopaholic (I'd classify Shopaholic Ties the Knot as more of the same).
