I want to know the answer to the following question:
Who wrote 'The Kidnapping of Edgardo Mortara'?
All the background I'm provided with is that "After completing filming on Ready Player One, while it is in its lengthy, effects-heavy post-production, he will film his long-planned adaptation of David Kertzer's acclaimed The Kidnapping of Edgardo Mortara.". Is that enough to answer the question?
