In Mercedes Lackey's "The Gates of Sleep", like in MacDonald's "The Light Princess", it is also the sister of the baby's father, this time named Arachne, who lays a curse upon the girl to die on her 18th birthday, even when Arachne was not supposed to possess any magical ability at all. The girl, named Marina, remains hidden during 17 and a half years until Arachne murders her parents and takes Marina with her. At some point, the curse is broken but Arachne manages to re-instate the curse, resulting in a battle between Marina and Arachne. In Robin McKinley's "Spindle's End", the wicked fairy is named Pernicia. Similar to the original fairy tale, Pernicia appears on the princess' name-day and places a curse on the baby, claiming that the child will, on her 21st birthday, prick her finger on a spindle and fall into deathly sleep. A powerful fairy named Ikor switches the identities of the princess, named Rosie, and her best friend Peony, to break Pernicia's spell when Rosie turns 21.
