The Seed Collectors by Scarlett Thomas. Great Aunt Oleander is dead. To each of her nearest and dearest she has left a seed pod. The seed pods might be deadly, but then again they might also contain the secret of enlightenment.
Mirabel Osler offers a stirring appeal for gardens that have lives of their own, that reflect not so much a compulsion for dominance and regimentation as an intimate understanding of natures own designs.
