Meanwhile, Escape...

In Poul Anderson's "The Queen of Air and Darkness," natives of an extra-solar planet entice children of human colonists into the wilderness where they create an illusory fairyland. Although these telepathic natives masquerade as Terrestrial "fairies," they are completely unlike them when seen as they really are. 

However, two other works by Anderson present more satisfying escapes from mundanity. 

Skafloc tells the Erlking:

"'I am wholly thankful to Imric that he rescued me from the dullblind round of mortal life. I am elf in all but blood, it was elf breasts I suckled as a babe and elf tongue I speak and elf girls I sleep beside.'"

-The Broken Sword, V, p. 35.

And, returning to an sf context, Diana Crowfeather runs away in:

Meanwhile Tigeries...

Many readers would gladly accompany Skafloc or Diana.
