This is one of those books that you just can't put down until you read the final page. The characters are so realistic, it's almost like they are real people instead of characters in a book. The heroine, Elizabeth, is not a milk-water miss, but a woman with morals and ideals. She has raised her sisters and brother for five years since the death of her parents until circumstances force her to come to terms with the need to marry so her family won't go hungry. The lady she works for, Lady Danbury, takes things into her own hands by asking her favorite nephew to come to her, not as the Marquis of Riverdale, but as ordinary Mister James Sidwell, to solve a blackmail plot and to meet Elizabeth. When the Marquis found Elizabeth with the book "How to Marry a Marquis" he thinks at first he's been found out. Then he offers to help her to practice what she's read on him. The dilemma-she has fallen head over heels in love with James Sidwell, but when he is revealed to be the Marquis as well, she believes he has been making fun of her the entire time.
