Lackey graduated from Purdue University in 1972. While at university, she began publishing work in fanzines and eventually sold a story to Fantasy Book Magazine. Around this time, she married but later divorced her first husband, Tony Lackey, and eventually married Larry Dixon. They live together outside of Tulsa, Oklahoma.
The basis of Lackey’s Arthurian novel, Gwenhwyfar, The White Spirit, was originally stimulated by the Welsh Triad (No. 56) entitled ‘The Three Guineveres’. She also incorporated elements of the ‘False Guinevere’ or Gwenhwyfach, and Triad 53 where it was stated that Gwenhwyfach struck Gwenhwyfar and thus caused the Battle of Camlann.
