40. Demon of River Heights ( https://www.bookcrossing.com/---/8164325 ), wild release, photo. Got a quick catch on it, too. (I'd previously released this well-traveled book in a local dentist office, and when I found it still there after 4 years I decided to move it; good thing I did!)
42. The Hitchhiker's Guide to the Galaxy ( https://www.bookcrossing.com/---/14436070 ), wild release, multiple challenges, photo. [It was purely by coincidence that this turned out to be my 42nd release for this challenge!]
"The truth is that even big collections of ordinary books distort space, as can readily be proved by anyone who has been around a really old-fashioned secondhand bookshop, one that looks as though they were designed by M. Escher on a bad day and has more
stairways than storeys and those rows of shelves which end in little doors that are surely too small for a full-sized human to enter. The relevant equation is: Knowledge = power = energy = matter = mass; a good bookshop is just a genteel Black Hole that knows
how to read. "
