I’m going to use an adjective to describe the fourth Guin Saga book, Prisoner of the Lagon, which might seem completely out of place for this most fast-moving and hard-hitting of adventures: introspective. After the full-bore action extravaganzas of the first three volumes, book four slows things down just a bit — but a slowdown here is akin to downgrading to “only” a Lexus from a Lamborghini. There’s still a lot happening between the covers, just in new realms.

Lagon gives us two parallel plots: Guin traversing the far reaches of the Nospherus wastes to enlist the aid of the barbaric Lagon in his fight against the Gohran armies; and intrigue within the ranks of the Gohran forces themselves. Each one ends up a fair distance from where it starts. The former storyline begins with Guin struggling against the elements and enemies of nature, but transforms into a vision quest within Guin’s memory and spirit. The latter presents us with what sounds like a sure-fire formula for gleeful mayhem: the cutthroat and cutpurse Istavan sneaks into the Mongaul army and masquerades as one of their number. But that story, too, evolves from one of subterfuge into something more unexpected and even touching.
