So, when Fern runs off to join the Wildheart Rangers - the protectors of towns from the spirits and ghouls of Dryda Forest - Nettle thinks she's lost her sister forever, as she'll never be brave enough to follow her into the enchanted woods.
Then news reaches Twigswick that Fern has abandoned the Rangers to join the infamous Shadow Stalkers and Nettle knows something isn't right. Fearing her sister is in danger, she ventures into the forest to find the truth . . .
