This devastating novel/film features two lab escapees—not old, but broken. Yet their relationship embodies "old soul" bravery. Snitter, brain-damaged and hallucinating, and Rowf, bitter and scarred, form a bond more loyal than any romantic couple in literature. When they finally swim toward the island (or death—ambiguous ending), they do so together. It is the bravado of two forgotten creatures refusing to die alone.

: A collection of short stories by Graham Renshaw that explores whimsical romantic relationships between birds, cats, and horses. Love in the Jungle
