Juniper and Hadley spend their days apprenticing at a bakery and performing at the local inn. But when a stranger makes an unusual order at the bakery, the friends set out on a journey to forage the magical mushrooms needed to make the requested pastries.

Along the way, Juniper and Hadley stumble across a mystery too compelling to ignore: Something has been coming out of the woods at night and eating the local farmers' crops, leaving only a trail of glowy goo behind. What started as a simple errand soon turns into a thrilling quest to save some furry new friends - and their caretaker, a fey named Thistle - who are in danger of losing their home.
