With her inheritance comes a stalker, a killer
…and maybe even Mr. Right.    

Science teacher Daisy Brighton’s inheritance incudes a rare and legendary gold bullion, rumored to be hidden in a Colorado graveyard. However, once she starts searching, what she finds instead is a murdered woman and gorgeous Park Service ranger A.P. Carter. Though she's a city girl and he's a mountain man, their immediate attraction explodes as they track down a serial killer…who plans to make Daisy his next victim.
