I've read quite a bit of Marion Chesney's Regency romances...I love a good Regency - I grew up reading them and I love the period/aristocracy/etc...
That said, I was kind of disappointed by The Ghost and Lady Alice. I thought the premise was interesting - Alice is a scullery maid who looks to the ghost of the deceased Eighth Duke of Haversham to rescue her from her plight. And...along the way...love blossoms.
I started the book with high hopes, but instead found flat characters with very little, if any, development and a plot that seemed way too far fetched (this coming from a fan of the paranormal romance genre too). The book just jumped into Alice's story without really creating her character...so, here you have a character that I felt rather "meh" about and then the plot just took off leaving loose ends in its wake.
At about a third of the way into the story, I grew tired of Alice and sped-read the rest of the book (which is why I placed it on the 'lemmed it' shelf as well). What was disappointing was that I am such a fan of Chesney and I felt as though this book did not live up to her other more well-known works.
