The Ear, the Eye, and the Arm Summary & Key Insights

Nancy Farmer's "The Ear, the Eye, and the Arm" is the second book in the Sea of Trolls trilogy, continuing the adventures of Jack Crookleg and his companions in a world blending Norse mythology and fantasy. The narrative picks up after the events of the first book, where Jack, a young boy ostracized for his unusual abilities, discovered a powerful, magical amulet – the Serpent's Eye – and found himself thrust into a quest to protect it.

This sequel shifts the focus to a journey across a vast and dangerous landscape. Jack, along with the powerful sorceress, Maris Piper, and the stoic warrior, Rolf, are on the trail of the monstrous troll known as the Master, who desires the Serpent's Eye for his own nefarious purposes. Their quest leads them through treacherous mountain passes, across treacherous seas, and into the heart of the troll's hidden kingdom. They are constantly pursued by the Master's minions, including a formidable group of shape-shifting draugr.

Along the way, they encounter a variety of fantastical creatures and diverse human settlements. They seek allies, encountering individuals like the enigmatic and powerful seer, the Ear, and others who offer assistance or pose further challenges. The book’s title itself reflects the acquisition of essential support; each part represents a key ally offering unique skills and perspectives in the battle against the Master. The Eye, represented by Maris Piper's exceptional magical abilities, provides crucial combat and protection. The Ear, through wisdom and foresight, helps the group navigate dangerous paths. The Arm, represented by a physical and powerful ally, provides needed strength and combat support.

The overarching theme of the novel revolves around the corrupting influence of power and the importance of choosing one's own path, even in the face of overwhelming odds. The Master's relentless pursuit of the Serpent's Eye demonstrates the destructive nature of unchecked ambition, while Jack's journey underscores the importance of resisting manipulation and making moral choices. He is consistently challenged by the temptation to rely solely on the amulet's power, ultimately learning to rely on his own courage and resourcefulness.

The relationships between the characters also play a significant role. Jack's bond with Maris and Rolf deepens as they face adversity together, fostering loyalty and trust. The narrative explores themes of friendship, loyalty, and the complexities of human relationships under pressure. While the fantasy elements are prominent, the book also delves into more profound themes of self-discovery, moral responsibility, and the struggle against overwhelming evil. The journey is not just a physical one; it is a profound internal journey for Jack as he comes to terms with his powers and his destiny. The novel ends with the party nearing their final confrontation with the Master, leaving the reader anticipating the climactic events of the third book.
