Severance

In 2089, an alien microstructure called the Lattice begins devouring Earth. Geneticist Linnea Moreau is torn from her younger brother and conscripted aboard an ark ship bound for a distant star. But when she discovers the Lattice has followed them into deep space—hiding in the colonists' very blood—she must race to understand its true purpose before fear and panic destroy the last remnants of humanity from within.
