True believer - Nicholas Sparks

Jeremy Marsh, a science journalist and debunker from New York, has set his sights on finding the real reasons behind the mysterious lights that appear in an ancient southern cemetery, and he heads to the tiny town of Boone Creek, North Carolina, in search of the truth.
