'We Called Them Giants' is a stunning little graphic novel that has a fairly fulfilling standalone story, though I would have been pleased to see this extended into a duology to further explore the interesting world that Gillen, Cowles and Hans have created. The novel has solid pacing and really gorgeous, vibrant artwork, I only wish that the atmospheric beginning of the novel was extended into a wider exploration of this dystopian world. Ultimately, I don't necessarily think that this book NEEDS any more volumes (I actually think the ending itself was poignant, succinct and discourages any sort of sequel!), but I would have liked to see more of these characters and watch them really develop their relationships further, especially so with the giants. 

Nevertheless this is a stunning novel and could appeal to a broad age-range.
