I found a solution on the weekend.
Big bag of corn chips. Big bowl of hot salsa dip.
Put feet up with book, eat chips and fiery dip.
Wipe occasional blobs of salsa off the book.
That simple method allowed me to knock off another 100 pages in one hit until I was struck by Monkey Interuptus.
It's good (the book, not the salsa). Really good. But it makes me glad that I am not a rockologist.
