The first 2015 publication of Doppler Press was Heather O'Malley's

Geoff Greenfelder's discovery should have changed his life by rocketing him up the ladder of academia . Instead, it changed his life in ways he never could have imagined. After partaking in a sacred ceremony by the Amazonian tribe he discovered, everything in his life changes, including his very own body. What should have been an occasion for joy becomes a trauma Geoff must work through. His only hope for returning his life back to normal is finding the answers that lie in unraveling the mysteries of the tribe before he can return to it.
