SOLVED. A short sci-fi book which may be by a Bulgarian author. [s]

So the book I have been looking for, for the past few months is a short sci-fi story about a group of humans travelling on a space ship after the Earth was destroyed. They have been travelling for many generations and gradually the women have died out leaving several men and children. The story centers on one of those children and how he misses his mother. The crucial point in the story was how they encounter a wormhole that sends them back to past Earth where they stay and live among the ancient humans and it turned out that they were the ancestors of blue eyed humans. I am 80% sure that the book was written by Bulgarian autor, a woman, and I read it around 2010-2012. Also its published version was strange since it was double sided- it contained both a ver in English and Bulgarian.
