People are talking...

"Marlena, thank you profoundly. I've had good editing. I've had great editing. Your editing is the best I've known. Your attention to detail is smashing. Your ideas are full of vitamins. The book you're helping me to create will be explosively better (i.e. more useful) for the reader. 
Respect, regards and immense gratitude, Tom"
