I have vastly enjoyed your books, and read several again and again.I am a retired military Dr, with some considerable trauma experience. Please note!. Penetrating chest injuries do not cough blood, as they bleed into the chest cavity.  And penetrating abdominal injuries do not vomit blood, they bleed into the abdominal cavity. However, the lay public probably enjoy the drama of visible gore more than concealed internal bleeding.

Keep up the good work .How about a naval series??
