''Serafina’s hunt leads her into the very forest that she has been taught to fear, where she discovers a forgotten legacy of magic. In order to save the children of Biltmore, Serafina must not only face her darkest enemy, but delve into the strange mystery of her own identity.''

Sounds like this could be our witch... It is possible Adam and/or Eddy knew of the book (they have kids), and so decided to use the name Seraphina for the witch, but I don't think it is a direct link.
