Não consegui encontrar uma prévia do livro on-line, mas a reimpressão do Hellflower (Butterfly e Hellflower) é referenciada em Promessa do Infinito por Robert Richart :
Paladin is the name of a "Library", a black box which was once the Library Main Bank Seven of the Federation University Library at Sikander Prime. Now Paladin is installed on a starship owned by Butterflies-are-free Peace Sincere, known as Butterfly for short.
