You Let Me In by Camilla Bruce
My rating: 4 of 5 stars
Ok. This is a weird one, and scary, and disturbing, and very open ended -- how reliable is the narrator?
Does the reader choose to read this as the narrator is telling the truth, and so you need to believe in evil fairies and a world of dark magic?
Here's the story: Cassandra Tipp, famous author, disappears, leaving a manuscript for her niece and nephew. It tells her life story, the truth behind not just her writing career, but also the tragedies:
Her murdered husband.
The murder/suicide of her father and brother.
So either dark fairies have haunted her and her family; or, (as one of her doctor's suspects) something terrible happened to Cassie as a child and the "fairies" are the way her mind dealt with the unthinkable.
I know what I think! But this works either way, with clues and evidence that support both readings.
