Back in October 2006 I read on someone's blog (was it JenClair's book blog? nope, just checked) about this book. I do remember it was for the R.I.P Challenge. I just surfed a couple of the blogs I read daily and could not find the reference to this book. Whatever. Thank you to whoever recommended it!
The Woman in Black: a Ghost Story by Susan Hill. This is a great ghost story! And rather than take up bandwidth writing a mediocre report, just go to Amazon.com and read the reviews. This little book of 138 pages is riveting and a quick read.
