I have so many books “in progress”. Some are closer to finished than others. Right now for example I have bookmarks in 11 books (!!):
Angel of Darkness (Carr)
Birds of Passage (Sole)
Darwinia (Wilson)
Dirt, the ecstatic skin of the earth (Logan)
Haunting of Hill House (Jackson)
Life of Pi (Martell)
Lord Valentine’s Castle (Silverberg)
Magic Labyrinth (Farmer)
Ocean Sea (Baricco)
Positively Final Appearance (Guiness)
Right Ho! Jeeves (Wodehouse)

And there may be one or two more in my desk at work… This is why one shouldn’t work in a library.
