First and fair warning, I would definitely look at the trigger warnings for this one.  Here are the main ones I noted: Suicide, Suicidal thoughts, self harm, child death.  

My eyes didn't stay dry for long while reading this book. Chris's pain of losing her son is so palpable.  And so is her love for him.  This is a fantastic, horrifying novella.  The writing is excellent, and the story instantly sucked me in.  I couldn't stop reading.
