Caught up on Hilda on Netflix? Craving more adventures with your favorite blue-haired Sparrow Scout? This is the book for you! Meet Hilda: explorer, adventurer, avid sketchbook-keeper and friend to every creature in the valley! Newly initiated into the Sparrow Scouts, Hilda is ready to explore and document the wilderness, and perhaps even make some human friends. Yet as luck would have it, there is a dark, menacing creature afoot near Trolberg, and Hilda is whisked back home to safety. Even so, intrigue seems to follow our blue-haired heroine wherever she goes, and it seems we may finally discover why so many socks in Trolberg seem to lose their mates.
