Thamiris had a great LJ entry recently about how, unlike a short story, a novel has the luxury to indulge in description and detail, to follow its own winding path without the need for economy of prose or plot. Resmiranda's Shadows Trilogy (Harry Potter) is exactly this kind of novel. It's about Hermione, Snape, and magic, but not like you've ever seen them before. It's an ambitious story, with some intriguing concepts about how magic in the Potterverse works, the process of redemption. Each sentence is a full-body caress of water, the writing rich and layered and intelligent. For the discerning reader, there is more depth here than a fathomless ocean.
