The Once and Future Witches

by Alix E. Harrow

The wayward sisters, hand in hand, Burned and bound, our stolen crown, But what is lost, that can’t be found? The rhyme their Mama Mags once sung to them, the verse hidden in the Sisters Grimm. Except this time the words keep going: Cauldron bubble, toil and trouble, Weave a circle round the throne, Maiden, mother, and crone.

if this sounds familiar, it's because it was partly stolen from macbeth--"we weird sisters, hand in hand," and "toil and trouble, fire burn and caldron bubble"--and partly from coleridge: "weave a circle round him thrice."
