Paint by Magic (Time Travel Mysteries (Prebound))

Something is terribly wrong with Connor's mom. She is uncharacteristically wearing old-fashioned clothes and cooking dinner from scratch, and she has removed all of the TVs from the house. What's even more troubling is her descent into increasingly disturbing trances. Connor suspects that an old art book with paintings of a woman who looks exactly like his mom is the key to her strange behavior. But because the artist who created them died before she was even born, he's not sure what the connection could be. When Connor is unexpectedly transported back to the 1920s, he realizes that it's up to him to solve the mystery--and to break the evil hold an obsessive artist has over his mom.
