Choke by S.R. Johannes
When Eria escapes her home in the Biome, she uncovers more about her
features and specifications as a HumaNot. Following her father's
instructions, Eria embarks on a journey into a dangerous and unpredictable world.
Along the way, she encounters a young rebel, Dirk, who explains he's from the Anarchy, an underground human resistance rising up against the BOTs--advanced man-made robots gone wild. Together, Dirk and Eria battle underground serpents, desert dingos, sand storms, and advanced Bots that are always hot on their trail. As they become closer, Dirk reveals his hatred of machines, forcing Eria to hide the secret of what and who she really is.
When the truth of her identity comes out, Eria is forced to become the very thing she hates the most.
