Jump Point by Ophelia Sexton

He can protect her from anything…except himself.

Bear shifter and smokejumper Mike Nakano is secretly in love with his friend and teammate, coyote shifter Kara Latrans. He’s quiet, serious, and extremely reserved. She’s bubbly, confident, and a notorious practical joker on their smokejumper team. Complicating things is a history of bad feelings between their different shifter lineages.
He doesn’t want to risk their tentative friendship by confessing his feelings for her. But all that changes when the two of them are sent to fight a fire in Denali National Park, and forced to undertake a grueling trek across the untamed Alaskan wilderness.
As they face hardship and danger together, Mike is driven to protect the woman he wants as his mate—but can he save her from his own desires?
