Destination: Sofia

Another Solid Maddock and Bones Outing. In this book, Dane Maddock and adventure partner Bones Bonebrake find themselves on an all expense paid trip to Bulgaria to investigate the Tsarichina Hole, courtesy of the Bulgarian government. The usual extreme sports, mystery, and action - along with a bit of historical oddities - come into play, and we get another solid entry into this world. Good enough entry point into the series, with references to previous events but primarily focused on the current events, and also solid for long time fans. Very much recommended.
