Larva is an account of a masquerade party in an abandoned mansion in London. Milalias (disguised as Don Juan) searches for Babelle (as Sleeping Beauty) through a linguistic funhouse of puns and wordplay recalling Joyce's Finnegans Wake. A mock-scholarly commentary reveals the backgrounds of the masked revelers, while Rios's allusive language shows that words too wear masks, hiding an astonishing range of further meanings and implications. Larva revives a Hispanic tradition repressed for centuries by introducing the English tradition of puns, palmodromes, and acrostics, and establishes Rios as the most accomplished successor (in any language) to Joyce.
