Sea-Kings of Mars
One of the finest anthologies I happen to own is Sea-Kings of Mars, which collects most of Leigh Brackett’s best short work. Not ALL, but it’s a great sampling. I’d only replace one or two of the weaker ones with other favorites of my own. If you happen to see a copy, grab one, because it’s out of print and prices seem to be climbing.
If you don’t prefer to have a book, you can get an e-copy of Leigh Brackett’s stuff from BAEN’s online site for ridiculously cheap prices.They also have a collection titled Sea-Kings of Mars, but it’s not the same collection. It’s still good, though.
