This is a great end to an interesting series. As always, I encourage you to have every book in the series in your posession before you start the first book. I only tell you this because you will grow impatient for the next book;and reading them in order is important.
A little better than Ways to Be Wicked, but not much. Julie Anne Long's style of having almost no interaction between the hero and heroine in the first 150 pages is unbearable. Pages upon pages of absolutely. Nothing. Happening. The story doesn't really progress and the hero and heroine aren't getting to know each other, because they are never in the same room. This doesn't build up to love, it just causes the reader aggravation.
A particular nitpick in this story, the hero, Earl of Rawden, is a notorious poet who writes under the nom de plume "The Libertine". Since so much is made of his licentious poetry, and his ability to seduce women with his words, it was a shame that we saw only a single sentence of his poetry. It felt like a cheat to keep referring to his steamy words and never read a one of them.
The finale to the Holt Sisters Trilogy is adequate. There is resolution to most of the overarching mysteries of their father's murder and mother's subsequent decampment. The three sisters get their HEA and most everything is wrapped up in a nice bow. Just wish it was more fun getting there.
