Black Market (Olesia Anderson, #2)

It seemed to have a better flow than the first and I liked the interaction between the characters--hearing/reading more about Sparks was fun--and Brad was an interesting match for Olesia.
I was really into this story and was disappointed when it ended but as with the first, you get one of those endings that makes you want to read more and I do--and I am!
Thank you D.D Marks!
