This companion to His Dark Materials and The Book of Dust offers a tantalizing new glimpse of Lyra and her dæmon, Pantalaimon. The world-changing events of The Amber Spyglass are behind them, and Lyra and Pan find themselves utterly changed as well. In Serpentine, they journey to the far North once more, hoping to ask the Consul of Witches a most urgent question. This brand-new story, a beguiling must-read for Pullman fans old and new, is a perfect companion to His Dark Materials and a fascinating bridge to The Book of Dust.
