So it's off to the random number generator. I have 765 books on my TBR shelf at the moment, so I enter 1 as the min and 765 as the max, and hit Generate.
Drum roll, please!
That's new! This is the first time my random number has been so low that it's in the part of my list reserved for review copies and other books I need to read soon-ish. So this month, instead of reading a random old book, I'll be bumping up a review copy to the head of the queue.
