The Elephant in the Room by Holly Goldberg Sloan

It’s been almost a year since Sila’s mother traveled halfway around the world to Turkey, hoping to secure the immigration paperwork that would allow her to return to her family in the United States.

The long separation is almost impossible for Sila to withstand. But things change when Sila accompanies her father outside their Oregon town to fix a truck. There, behind an enormous stone wall, she meets a grandfatherly man who only months before won the state lottery. Their new alliance leads to the rescue of a circus elephant named Veda, and then to a friendship with an unusual boy named Mateo, proving that comfort and hope come in the most unlikely of places.
