@sinbach Thank you for sharing this. I look forward to reading it! I think there is a typo on the sale price on Amazon and I wasn’t able to find a way on Amazon to alert them. It says the cost is over $16,000. Perhaps you could let Dr. Johnston know? Luckily I put slightly different words in the search and discovered that the book was listed twice. Other people might not see that and pass on buying it. Thanks!
