If Emily Edwards knows one thing, it's that you don't go to a remote island by yourself. Ever the type A personality, Emily doesn't want to hike around an unfamiliar island, but she's determined to fulfill her late father's national park bucket list, starting with Isle Royale National Park--home to wolves, bears, and hundred-year-old shipwrecks. She has no choice but to hire a tour guide, and there is only one that isn't booked solid.

Ryder Fleet, co-owner of Fleet Outdoor Adventures, wouldn't call himself a wilderness expert, and he definitely doesn't know how to find true north. But when his dormant adventure guide business suddenly finds life again after a random inquiry, Ryder somehow finds himself on a ferry to Isle Royale with a very beautiful, no-nonsense woman. What this woman doesn't know is that his brother Caleb, who died two years ago, was the outdoorsman of their business, while Ryder just did the marketing. But how hard could it be to hike up a few mountains?

Pretty difficult, actually, when murder is involved. Emily's perfectly planned trek turns disastrous when she and Ryder witness a brutal crime and are suddenly forced to evade a group of archaeologists on the hunt for a jewel. As they spend nights together too close for comfort, they realize their shoddily built fire isn't the only thing that's kindling, and that they must trust each other if they want to escape the island with their lives--and hearts--intact.
