The seventh in the Honor Series All Cameron Roberts and Blair Powell want is a small intimate wedding, but the paparazzi and a domestic terrorist have other plans. First Daughter Blair Powell and her lover Cameron Roberts, newly appointed deputy director of the Homeland Security Office, escape to a ski chalet in the Rockies after a harrowing attack by members of a domestic terrorism organization. Under orders from the White House, Blair reluctantly allows a member of the “enemy camp,” investigative reporter Dana Barnett, to join her inner circle in the hopes of limiting her media exposure. Dana isn’t any happier about being pulled from her coverage of the escalating conflict in the Middle East to write a society “fluff piece,” although the presence of beautiful Dr. Emory Constantine does make the assignment a little more enticing. With the nation under attack, the world on the verge of war, and their personal lives the focus of intense public scrutiny, Cam and Blair come under fire both publicly and privately when an old nemesis resurfaces intent on finishing his holy mission—to kill Blair Powell.

The interactions between wild bird populations (many protected by law) and fish, particularly those under commercial culture or part of a fishery is subject of much controversy. Ecological, environmental and conservation pressures run alongside commercial pressures on exploited fish populations. This exciting book draws together contributions from all over the world to provide a fascinating insight into many case studies and conflicts in managed situations as well as looking at the overall ecology of such interactions in normal un-managed ecosystems.
Fishing provides food, income and employment for millions of people. However, fishing has environmental costs that threaten rare species, marine ecosystems and the sustainability of the resource. Based on the research expertise of leading scientists, Commercial Fishing: the Wider Ecological Impacts provides a lively, timely and accessible account of fishing activities and their impacts on marine habitats, biodiversity and species of conservation concern. It covers fishing methods that range from trawling in the Antarctic to fishing with dynamite in the tropics. The authors show how habitats such as the muddy sea beds of the deep sea, kelp forests and coral reefs are affected by fishing and how birds, mammals, turtles and sea snakes both suffer and benefit from fishing activities. They also look to the future, highlighting ways to make fishing gear 'environmentally friendly' and asking whether marine reserves will improve conservation.
