El mismo mar

 There was a novel very well known at the time, El mismo mar de todos los veranos.  It doesn't seem to have last--no new editions or critical studies. Esther Tusquets, the author, was very well known and this was the first of a trilogy.  The title is memorable because it is a perfect eleven syllable line of poetry (if it were a line of poetry.) Another novel in the series is "El amor es un juego solitario" which follows the same metrical pattern.
