The continuing adventures of Liam and Ondry. No really. 
 This series is brilliant because it really outlines the differences in culture and language and how easily something could be misunderstood. 
 In this particular book, we are introduced to a new human character, Captain Susan Diallo, who's specialty seems to be linguistics and first contact. However, while she may be a quick hand at languages in general, she doesn't understand the Rownt themselves and therefore, offends without meaning too. She also seems to have an ulterior motive. 
 This book was filled with intricate social and societal complexities and continues to explore the very different thought patterns of human and Rownt behaviour.
