Rainbow Mars was a fun read, so long as you understand it's fantasy, or at best science fantasy-- a far cry from Niven's usual "hard" SF! I must say I was irked by the depiction of Wells' Martians' as "octopus-like". No no no-- they have two bunches of thin, whip-like tentacles, one at each corner of their mouth, but overall they're huge heads without bodies-- a far cry from an octopus!
