The secret of the house is opposite (#1). Ryder D.

Jack lives in a hill house and often feels lonely. Once during the summer holidays, he climbs with neighboring boys into an old abandoned house overgrown with ivy. But soon the guys understand that ivy hides not only the walls... A girl lives in the house, who does not even remember her own name! And in general, magic is happening in the house! Painting comes to life, animals talk, and it turns out that Jack and mysterious girl are connected by a common secret!
