Query: Excellent book---terrible proofreading

This is my third book by Ackerman. The book is excellent. He simplies the details and maintains the readers attention. With the current mortgage meltdown, it's good to know that these things have happened before and the country survived and moved on. BUT . . . (you knew this was coming) I have never seen a book with so many typos. That is inexcusable. Grate arther, good stori, ect., but thos tyops---
