The Hidden Tunnel - Pohler, Eva

It's hard to say no to a handsome billionaire... Ellen, Sue, and Tanya travel to Portland, Oregon where a local billionaire has promised to give them his current renovation project--a historical carriage house in the downtown area--if they can find his missing brother. As they dig deeper into a local legend, they soon fear that the cause of the brother's disappearance is more sinister and more powerful than ghosts. ¿
