"You did it, baby. The book is excellent, the writing brilliant," Oswalt wrote. "You tried to bring kindness to chaos, which was your way. #IllBeGoneInTheDark #MichelleMcNamara."

The comments were immediately flooded with replies, including from Mae Whitman, who shared a bushel of heart emojis followed by, "cannot wait to read."

Another commenter tweeted, "I was doing fine until I read the word 'perfect.' What a great way to honor her," which was replied to with, "This, exactly this. Now I'm all tears."
