Certain Dark Things had a good plot, was bloody and gory, and funny at times.  I liked the action, but it was too quick. It started quick and then was over before you knew it.  I do like this book is not afraid to kill people.  And the love story didn’t seem plausible and was jumped into quickly.  I was sympathetic to both Atl and Domingo, but Domingo is an idiot that jumps into stuff way too quickly. Book needs some more fleshing out to be really great.
