Prue McKeel's life is ordinary. At least until her baby brother is abducted by a murder of crows. And the things get really weird. You see, on every map of Portland, Oregon, there is a big splotch of green on the edge of the city labeled "I.W" This stands for "Impassable Wilderness." No one's ever gone in---or at least returned to tell of it. And this is where the crows take her brother. So begins an adventure that will take Prue and her friend Curtis deep into the Impassable Wilderness.
