Goblin Night, by James H. Schmitz

James Schmitz's fiction was well-aimed at adolescents. I kind of wonder how his mostly male readers would have reacted to his very capable 15 year old female protagonist in 1965. In Goblin Night, she vanquishes an evil latent psionic with her own powers. The other fun story elements are a nightmare figure (a goblin, a horror vanquished during earlier planetary settlement) and an ultra-capable fighting dog. It's another fun little read, a period piece.
