Alien: Echo. Grant M.

Olivia and her sister - Gemini Viola dragged the universe as much as they remember: their parents, well -known xenobiologists, always give up the researchers of other worlds. Only now, having settled in a new colony, they are faced with an alien threat, not similar to anything seen or described before. And the usual world of the sisters is collapsing in an instant.

Olivia knows: her only weapon in the colony covered by chaos is knowledge of xenobiology and determination to protect Viola. In addition, a shocking family secret is unexpectedly revealed - in their own no less terrible thing than bloodthirsty monsters around.

And they, penetrating the rich wild nature of this untouched colonial world, begin to adapt quickly. So Olivia will also have to adapt if she wants to survive...
