The Stranger Next Door: A Jenna MacKenzie Mystery

Ten-year-old Jenna MacKenzie is having an ordinary summer - reading books and cooking up treats with her friend Anna-until the school burns down and a mysterious stranger moves in next door.
Jenna is convinced that Mr. Stoker (just like Dracula!) is up to no good, and she is determined to prove it-even if it means defying her parents and dragging Anna along with her-against Anna's will!
