About "World", I always have to think whether UKL first conceived the title in German, "Das Wort für Welt ist Wald" (not my idea, but a close friend's who read it in his native German first).

What's the third big book? The Earthsea series? I imagine two must be LHoD and The Dispossessed, the latter of course a favorite among theoretical scientists.

OT I first had vacations in the mountains at twelve, but I spent my summers as a child camping in an organized camping place near the sea until about that age. Three months per year - Italy has long summer holidays.
