'Return to the Spine' is the follow-up to 'Beneath the Spine', reviewed by my good self back in August 2003. The author, Seryn, has built up something of a reputation for creating action-packed adventures based in the Forgotten Realms, and this offering marks his fourth foray into the hallowed lands of Faerun. While not as epic in scope as the prequel, 'Return to the Spine' is a more refined and story-driven module, although it shares the strong linearity of its predecessor.
