Borne / VanderMeer, Jeff

"The humans are Rachel and Wick - a scavenger and a drug dealer - both with too many secrets and fears, ready with traps to be set and sprung. The creatures are Mord and Borne - animal, perhaps plant, maybe company discard, biotech, cruel experiment, dinner, deity, or source of spare parts"--Provided by publisher.

A young scavenger named Rachel explores a post-apocalyptic world in a constant search for supplies. One day, she finds a sentient green mass she calls Borne that she decides to keep and raise as her own. As Borne grows, Rachel comes to realize the significance of the strange creature and its potential impact on the world. But other forces see it too, and Rachel must face surprising enemies to keep Borne safe.
