I can rarely predict what books the younger Princeling will like. I was so surprised and delighted that he liked Ancillary Justice since usually he is all about the sword and sorcery.

He loved all the Five Gods books by Bujold, for example, and has been waiting impatiently for more.

But I couldnt' get him interested in the Vorkosigans.

No idea how it works for him. Recently he read Empress of Timbra and really liked it.
