Summary: Petunia Dursley might not want her nephew to live with her, but she did care about what might happen to him, and she had other resources. That made all the difference. When Harry Potter is left at her doorstep, Petunia calls her cousin, Wanda Evans Holmes. In doing so, she changed the course of more than one future, throwing Albus Dumbledore’s plans awry with the Holmes Factor.
