Stella is upset when she finds out she needs glasses. But then it turns out her new glasses are magic! When she wears them, Stella can see the sparkly night sprites. In this first book, Stella meets Trixie, a knit-knotter sprite. Trixie seems nice, but she ties knots in kids' hair to make it all tingly-tangly. If Trixie doesn't stop tying knots, Stella will have to get a haircut! Can Stella stop her magical new friend from turning her hair into a tangled mess?
