Mini review of Dogs of War by Adrian Tchaikovsky

Genetically and technologically enhanced animals, mostly dogs, have been developed as mercenary soldiers who act on any order given by their masters. Rex is such a soldier, leader of his squad, but what happens when his enforced obedience is removed and he is able to (has to) make his own decisions? This is a fascinating book that probes the ethical boundaries of enhanced biological beings, AI, and free will. I really loved this one and will certainly read the other the books in the series.
