'Here', my new New Adult novel

Here's the working plot summary for the book jacket of my brand new YA novel Here:

"Twenty-four year-old Sam Henderson is asked to housesit La Porte Grise, a Gothic Revival mansion in his small hometown of Ferring, New York. When Michelle Lowery, a secret crush from his highschool days, returns to Ferring after a six year absence, Sam invites her to stay in the fully-staffed home.  As they navigate budding careers, romance and Facebook, Michelle keeps seeing a face staring out from a fourth floor window.  A face belonging to someone no one can find or explain. Sam begins to ponder whether Michelle is losing her grip on reality or if La Porte Grise hides a secret all its own."
