[In Dragons in the Waters] L'Engle writes a taut, intricately layered novel, charged with suspenseful twists and faceted into a thoughtful yet climactic conclusion. As in her other books, the power of love and cohesive force of caring are underlying themes, and the perceptively drawn characters, some of whom appeared in The Arm of the Starfish, are realistic in their conception, credible in their actions, and extremely human.
