Welcome To WDC"Newbie Welcome Wagon" 

Hi BBK,
You have improved an already wonderful story. I loved it. The tone is full of tension and fear. It grabs all the reader's attention and makes them want to read on. The reader is pulled along by suspense. They will read on to see if Prerna will find the companionship she seeks. The plot is straight forward and moves along logically. The story is about a woman who finds new strength out of heart break. The conflict is well defined. There is no doubt about what is going on here. The characters are well developed and believable. They come across as real people. The dialogue is well done and realistic. The characters speak like real people. The description is detailed and vivid. You have included much more description in this revision. It makes the story even more vivid and puts the reader all the way into the story. The story is well structured and consistent in terms of point of view and tense.
As for your other question, yes this story is contest ready. Right now, the "Newbies ONLY Short Story & Poem Contest"  is accepting entries. You might consider entering this story.
Great job.
