Rayne's Kids (Go On A Snipe Hunt)

Now, this I might read.

Threesome? ^_~

(This I doubt, however.)

And yes, third commenter down, they most certainly ARE named for Pollux and Castor; the Discouri are the gods of knights. Featured on the coinage, and they were prominent for a while as Roman powers tended to be.

Pollux was also called Polydeuces.

By the wayside, lux = "light", continuing the tradition of naming the Tam girls with nouns. XD
