I fell in love with the Murphy family and asked the author to read the rest of the series, which she kindle sent me.
I loved them all for different reasons, but mostly the hot steamy sex and the details of the jobs the main characters have and how detailed they are when explaining how the job is done. The men are so varied in their careers, love the travel also.
And there is one book featuring Ryan that is online. I love that I could read the whole series without having to wait months til the next one was written.
I don't have a favorite but like them all extrememly well.
