Interesting and witty.
Joanna Walsh brings to her writing the same sensibilities and sense of reader inclusion as did E.B. White. A unique perspective, the stamp of originality and yet somehow summoning the ghost of a sentiment (of a bookself) that is within all readers.
Being a book-hoarder myself, this story made me smile. But, though I am a baby-boomer, my bookshelf does, indeed, change, though my parents' didn't.
Having switched to a kindle, my bulging bookshelves are a thing of the past, and the ghost is in the e-reader, commenting on my unread purchases.
