H.M.S. ----

H.M.S. -- suggests that the novel might revolve around a British naval vessel possibly during a specific historical period or naval conflict. Without further details or a synopsis of the novel it's challenging to provide a comprehensive summary or analysis. However based on the title alone one might expect themes of naval adventure camaraderie and perhaps even maritime conflict to be explored within the narrative. It's also possible that the novel may touch upon broader themes such as duty honor and sacrifice which are often associated with stories set at sea or within military contexts. Overall H.M.S. -- by John Graham Bower remains intriguing and readers interested in maritime fiction or historical novels from this time period may find it worth exploring despite the limited information available.
