I don't know why I stopped with the Wallflower series she wrote. This book is kind of a prequel to that series and so wonderful to boot! 
 The story of Aline and McKenna reminds me a little of one of Jane Austen's stories. Aline and McKenna grow up together. He's a servant and she's nobility. But they love each other and they are separated. This book made me sad and happy and wistful. It was a beautifully written story that did contain a little smut but not overly so. The bases was really the relationship and the pain that both characters have. 
 In addition to Aline and McKenna, there is Livia and Gideon Shaw. Livia is Aline's half sister (their mother was unfaithful) and has suffered a serious loss. Livia's loss combined with a scandal has caused her to remove herself from any company much to the dismay of Aline and their brother Marcus. But Livia can't seem to resist the drunkard millionaire Shaw who seems to have some kind of internal pain. Their story is also very beautiful and I suspect the stuff of another novel.... Which I'm going to look for. 
 Lisa Kleypas writes beautifully and makes it seem like these characters have very rich lives except that they live superficial ones until opening up to the one person they will truly come to love. I think Kleypas's stories are a cut above most romances and very much worth reading.
