Funny thing about 'underrated': Lem half-agreed. From his own note on Eden: 'From today's perspective Eden is neutral in my eyes. It is so-so ... a rather unsuccessful book; its characters tend to be schematic.' The same official page calls it the book that opens his mature science-fiction.

Which lands your read harder, not softer: he wrote the procrustics under real censorship, and still thought he'd built the frame badly.
