Juan Miguel Aguilera (born in Valencia in 1960) is a Spanish science fiction author.
These are histories influenced by hard science fiction, set in the universe of Akasa-Puspa, although the time gaps between them make the similarities harder to find.
Mundos en el Abismo (Worlds in the Abyss) and its sequel Hijos de la Eternidad (Children of Eternity) combine a plot typical of space opera with elements of hard science fiction.
[1] El Refugio (The Refuge) shows a deep scientific influence: biotechnology, biochemistry, communication between species, evolution.
In his solo work, he spends less time on scientific detail and incorporates elements of fantasy, in a genre he calls "speculative history."
