The Electric Philosopher reviews Phyl-Undhu (with promise of a Chasm review rashly added).
ADDED: As promised, and faster than could reasonably be expected …
There’s a fluent, elliptical, and remarkably thoughtful review of Phyl-Undhu at Dark Ecologies.
When they come battering on the door to beg for permission to make a blockbuster movie out of Phyl-Undhu, I’ll definitely recommend Scott Alexander for a cameo role as Alexander Scott, but that will be almost entirely in order to enjoy seeing someone playing a part so far out of character.
