I ended up getting like 20 titles into the sack, because they were all so slim, and it ws barely half full. They are all the way downstairs and I am too tired to go through them right now -- not least because at least half the ones I pulled were just to finish off my sell-to-Half-Price stack (I would feel bad about potentially taking them from others, buuuut, they kept pushing the bag on me, the sale was only going on 1.5 more days by the time I got there, and it was extremely not busy and had lots of stock left anyway).
Buuut I just had to announce that I took 1960s Scholastic book "Secret Under the Sea" for the sole reason of this line in the summary:
"It is the year 2013, and Robby lives in an Underwater Research Station with his scientist parents."
AND SOLD. I didn't even look at the rest of the summary and just realized I have no idea what it's going to be about, beyond some type of science fiction.
