Classic adventure for the modern reader! What secrets lie in the depths of Bulgaria's mysterious Tsarichina Hole? Aliens? Demons? Treasure? It's up to Dane Maddock and Bones Bonebrake to solve one of the strangest mysteries of the Twentieth Century. Dane and Bones have traveled to Sofia, Bulgaria to help their friend Max Riddle shoot a new documentary television show about the Tsarichina Hole, a shaft excavated by the Bulgarian military in the early 1990s, on the advice of a psychic remote viewer, and then abruptly sealed for no apparent reason. Riddle has found a back door into the excavation, known to many as "Bulgaria's Area 51," and asks Dane and Bones to help him explore the passage to nowhere. Their discovery of a prized relic belonging to a famed Bulgarian conqueror touches off a search for an even greater treasure, and threatens to expose a secret that someone is willing to kill to preserve. Praise for David Wood and The Dane Maddock Adventures! "Dane and Bones.... Together they're unstoppable. Rip roaring action from start to finish. Wit and humor throughout. Just one question - how soon until the next one? Because I can't wait."-Graham Brown, author of Shadows of the Midnight Sun "What an adventure! A great read that provides lots of action, and thoughtful insight as well, into strange realms that are sometimes best left unexplored." -Paul Kemprecos, author of Cool Blue Tomb and the NUMA Files "A page-turning yarn blending high action, Biblical speculation, ancient secrets, and nasty creatures. Indiana Jones better watch his back!" -Jeremy Robinson, author of SecondWorld "With the thoroughly enjoyable way Mr. Wood has mixed speculative history with our modern day pursuit of truth, he has created a story that thrills and makes one think beyond the boundaries of mere fiction and enter the world of 'why not'?" -David Lynn Golemon, Author of the Event Group series "A twisty tale of adventure and intrigue that never lets up and never lets go!" -Robert Masello, author of The Einstein Prophecy "Let there be no confusion: David Wood is the next Clive Cussler.

Talbot, author of 2012: The Fifth World "I like my thrillers with lots of explosions, global locations and a mystery where I learn something new. Wood delivers!
