Mercy Bidwell inherited two things from her late father: a journal detailing his quest for the fabled Silver Angel Mine, and his spirit of adventure. She plans on utilizing both those bequests to find the mine, thus proving to the world that her father, and his devotion to the mythical mine, wasn't crazy. She also hopes to obtain enough wealth so she can leave the dreary mining community of Paradise behind forever.
There are, however, a few small problems standing in her way. For starters, Mercy has no equipment - and no prospecting experience. Her uncle, superintendent of the Paradise Mine, is determined to keep Mercy safe. To this end, he hires Edward Cartier, a foreman for the mine and the most difficult man Mercy has ever met, to safeguard her on her expedition into the mountains.
While Edward is focused on the job that he is being paid to do, Mercy's faith and determination are infectious; soon he is as committed to finding the mine as Mercy. But neither Mercy nor Edward anticipate that the excitement and danger of their quest will lead to love--a love that will too soon be tested.
