Wildfire Book 2 [EPUB ebook] 

The U.S.S. da Vinci’s mission to salvage the U.S.S. Orion and the deadly Wildfire warhead has gone horribly wrong. Captain Gold and Security Chief Corsi are gravely injured, and the da Vinci is literally coming apart at the seams as it drifts further and further into the deadly atmosphere of a gas giant. Worse, the Wildfire device is armed and loose in the turbulent atmosphere, threatening destruction on a planetary scale. Commander Sonya Gomez and what’s left of her S.C.E. team must use all their skills to survive, complete the mission, and learn the deadly secret of the strange alien lights that will be either their salvation — or their destruction!
