These two titles ought to be sold as a pair based purely on their titles.
Deeper Than the Dead by Tami Hoag claims to be a New York Times bestseller. If so, why is it being flogged at discount rates on a book flyer? Hmm! The description says, "Three children and a young teacher make a horrifying discovery in their seemingly idyllic town: a corpse with its mouth and eyes glued shut. FBI profiler Vince hunts for the truth — but more victims might be found." More victims might be found? Oh my god! We'd better put this case on hold until we're sure no more victims will be found!
Meanwhile, in Choosers of the Slain by James H Cobb, "When Argentina launches an invasion to seize territory in Antarctica, Commander Amanda Garrett and the USS Cunningham must sail into hostile waters to stop them." Why? This is essentially nothing more than a rip-off of the actual hostilities between Argentina and the British some beers ago. Yawn.
