The Reaper's Harvest

I do not own Pendergast or anything related to the works of Douglas Preston and Lincoln Child! I do however own all the OC's and situations. A young psychiatrist with a checkered past if forced to join Pendergast on his latest case. A serial killer with a high body count and no limitations. Will Iris be able to help Pendergast or lose herself to the Reaper's fury. R/R, Rated M
