they created a family of three
For the formation of families they come together in groups of three, all three were different creatures, and each performs its functions in the family. I remember in the family was one of the main characters being female and two - a man. And sometimes - vice versa. On the cover of the book were drawn by these three creatures, as they are somewhere to go, one of them was a rectangular form. Sufficient to socio-philosophical book about the society.
