Opportunity Knocks - WhereDestiniesMeet17

I enjoyed the plot and pace of this steter fanfic despite the many typos. A monster is ripping out the hearts of teenagers in Beacon Hills and Stiles is determined to get to the bottom of it. The epilogue was weird, seemed like the plot for a sequel crammed into one chapter.
