The Babylon Eye - Linked Worlds, #1

Elke Veraart is in prison. She used to be an eco-terrorist, hunting down poachers to protect endangered species. Now she's facing the grim reality of life behind bars. Just as Elke is about to give up hope she is offered a chance to win back her freedom. All she has to do is find a missing dog. Meisje is no ordinary dog. She's cybernetically enhanced, a valuable living weapon. She's also lost, hungry, and alone.
As Elke closes in on Meisje she finds her admiration for the resourceful cyber-dog growing. And Meisje begins to wonder if she could trust the woman on her trail. Then Elke discovers that she's not the only one hunting the cyber-dog, and that her orders have changed. She must do more than find Meisje. She has to kill her. Elke has to make an impossible choice: her freedom, or Meisje's life. Or is there another way? It's risky, but Elke could use the secrets she's uncovered to save them both.
