One girl is dead.

The other is haunted.

From the outside, Windham-Farnswood Academy is beautiful, prestigious, historic--the perfect place for girls to prep for college. But every student knows that all is not as it seems. There is a spirit who haunts the old senior dorm. She is called the Winter Girl because she comes knocking each January.

For Haley, the timing couldn't be worse. This month marks the one-year anniversary of the death of her ex-best friend, Taylor. When a disturbing video of Taylor surfaces, new questions about her death emerge. And it actually looks like Taylor was murdered.

Now, as Haley digs into what really happened last year, her search keeps bringing her back to the Winter Girl. Haley wants to believe that ghosts aren't real, but the clues--and the dark school secrets she begins to uncover--say otherwise. It's up to her to solve the mystery before history has a chance to repeat itself and another life is taken.
