Summer Ice was the mate of Darkwalker of the Red Fern and mother of Moonflower and Hawksbill. It can be assumed she was a lamia vampire, as both her mate and her children were lamia and ancestors of the Redfern family.
- Summer Ice is a traditional lamia name. 'Summer' refers to the season that comes after spring and before autumn, usually the warmest time of year. 'Ice' refers to frozen water. Summer Ice's name is somewhat contradictory, as summer is usually associated with heat, whilst ice is cold and associated with winter, the coldest time of year.
