Child-Parent Relationship Therapy (CPRT) Treatment Manual: An Evidence-Based 10-Session Filial Therapy Model

Hello I am very pleased with my purchase except I do not know where to get the access code for the Companion Website. The book came in great condition. However, it is unclear how to access the Companion Website or online materials. Is there a code inside the book or was there a code I was supposed to receive separately? Please let me know, otherwise I will sadly have to return the book. Thank you!
