Yay! My favourite Heinlein ever,
Citizen of the Galaxy, now not only in e-book, but also DRM-free
and MultiFormat
and sale-priced at Baen's marvelously reasonable terms.
Plus
Tramp Royale, for which I still haven't been able to locate wherever I put my paper copy, and is a really fun read, even if he does get kind of off-topic ranty at times.
This calls for the dance of joy.
<-- okay, this is more like Dance Dance Restriction, but close enough.
