While I love this series and I will always find myself attached to L.A. Meyer's delightful characters, this book is where the series goes down in quality, in my opinion. A few of the new characters, such as Fink, come across as two-dimensional and over-ridiculous. The language is often unnecessarily crude, and when all else fails in the plot, Jacky can sing a tune and everything will be fine again. There are a few ridiculous rabbit trails that took away from the main storyline, such as Jacky being welcomed as a member of a Native American tribe after a couple of days (because that's what has to happen if your hero travels west) and eventually being carried away by a tornado but otherwise unharmed. Some new characters were a joy, and I really did like reading more from Jacky, but compared to the first few in this series, Mississippi Jack disappointed me.
