Langenderfer, Kirsten
From Spearfish Lake Tales Wiki
Kirsten Langenderfer is a native of Spearfish Lake. Her original boyfriend was Henry Toivo although she later has children by, and then marries (in that order), Mike McMahon. Kirsten's refusal to marry only after Henry's remains are brought back from Vietnam is Mike's motivation in Absent Friend.
They live on Busten Axle Road and have three children Tiffany, Henry, and Susan. She has been friends with Jackie Archer since school. She has also been a member of West Turtle Lake Club and has worked as the Advertising Manager at the Spearfish Lake Record-Herald.
Kirsten kills a snake when in crawls out of a drain in the story Busted Axle Road. This is tentatively identified as a Gibson's Water Snake, which leads to a main thread in the book.
