stone soap (pg. 201) -- Hard to find information, but it looks like the Nazis gave the condemned fake soap when they went to the showers to be gassed.
persiflage (pg. 6) -- a frivolous or flippant style of treating a subject.
soletta (pg. 31) -- A hypothetical magnifying device constructed in space for the purpose of amplifying the solar radiation a planet receives, in order to generate power or aid in the process of terraforming.
delope (pg. 272) -- To fire a gun into the air in order to end a duel.
defenestrating (pg. 23)-- I ran across this word TWICE in the last book I read, but forgot to enter it. I'm SURE I've looked it up before, though. I ALSO just saw it in the current book I'm reading, which is book two of the book I read before this one, FYI. Oh, defenestration is the act of throwing someone (or something) out of a window. Good to know!
cantle (pg. 249) -- The raised rear part of a saddle.
Contents:
The Borders of Infinity
Brothers in Arms
Mirror Dance
I enjoyed this omnibus very much, even with the repeat of Labyrinth!
towhead (pg. 318) -- A sandbar or low-lying alluvial island in a river, especially one with a stand of trees.
Not a tidy heart shot, but that straw bale sure wasn't getting away. (pg. 197)
