Fragile Things by Neil Gaiman is a delightful cascade of both poetry and prose; and, as is rare with some authors, the poetry is neither contrived nor sloppy. Two stories in particular call out for attention: The Problem of Susan and The Monarch of the Glen. In Problem, Gaiman gives us a sample of all that is best about fan fiction, and spins out a tale of Susan, and how she spends her post-Narnia years. It is touchingly reverent and explains once of the difficulties I always had with Susan in the tales, wondering if she was a stand in for Judas, or if she was a placeholder for the non-believer. Gaiman handles her story with what feels like an accurate representation of how her life might have played out (with, I warn you, some elements unsuitable to the younger reader) and also adds in his own careful contribution of what life might be like for an old, proud woman who has experienced some extraordinary times.
As for the poetry, I delight in a well written verse but tend to most enjoy haiku and limericks; nothing too long and self-centered. Gaiman's poems twist and play with a theme delightfully and spin out a yarn until the threads remain, scintillating and microscopic for examination. Look closely at Locks, a poem about a father reading Goldilocks to his daughter, and it seems as though you can witness the scene, the bright young child tormenting her father with interruptions, the father enjoying the banter in spite of his attempts to keep the story moving, all while he ruminates over the different perspective he brings to the story from the vanatage point of age.
