*I received this book in a GoodReads First Reads giveaway.*This was an enjoyable start to a series that I look forward to reading more of. Edwina, the heroine, and her group of friends decide to save the world from a rake named Ashton who has placed a personal ad for companionship. They fear he is trying to lure innocent women in to ruin. This is how Edwina ends up sneaking in to Ashton's house and the start of a sweet relationship. Edwina is a wiz at cracking codes and cyphers, which was interesting and not something I've read before. I really liked Edwina and her friends that created the Rake Patrol. They were delightfully misguided together and sort of reminded me of myself with my friends when I was younger. I also like the fact that these ladies were not titled. They were in a social class that I don't often read about in historicals. I think one of the things I liked best about Ashton was that he disliked his reputation as Casanova and regretted his behavior when he was younger. He wanted to be seen as more than a rake and he wanted to prove he was good at something other than taking women to bed and I appreciated that about him. This one gets four stars instead of five mainly because the plot did get predictable in the second half of the book. I knew what was going to happen, but luckily the author wrote it in such a way that I still found it enjoyable. I do look forward to reading about the other members of the Rake Patrol, especially Sarah.
