I have consulted with the book-counting spider and here is the current tally. Books in bold are the ones I am now reading.
Over Sea, Under Stone by Susan Cooper
Cross and Burn by Val McDermid
Watch Out for Me by Sylvia Johnson
My Island Homicide by Catherine Titasey
Eureka by Peter FitzSimons
The Old Ways by Robert MacFarlane
The Butterfly Isles by Richard Bakham
White Beech by Germaine Greer
Until now, there has been no change to the configuration of book stacks on the desk/floor/other flat surfaces, because those four now-read titles are e-books. But Watch Out for Me is a yer actual paper book, so things will start changing.
