From Campbell’s preface to Rillera’s book we read regarding sacrifice:

• The set of equations at the heart of the PSA model is , quite simply , untrue . The practice and logic of OT sacrifice has nothing to do with substitution , retribution , or punishment ( i.e. , negative retribution ) . Neither is it supplying a universal account of justice . The mechanism , logic , and concerns of OT sacrifice are completely different . (16)

Hopefully this book will go to the heart of what many believe to be the core of the Christian faith, penal substitution atonement (that Christ died to pay the sin debt we owe), refuting them, and also that secular readings of Christian origins based on PSA such as the Christ Myth Theory are demonstrably false.
