His Summer Intern by Jessa Kane

Juno has been locked away for two years, but has finally escaped and is now on the run. While dashing through the forest, she comes upon a cabin. The owner, Caleb, is a young, former military man with tortured grey eyes—and he believes Juno is the summer intern he was expecting to help him with research on his novel. With no choice but to go along with his misconception, the two tumble headlong into a wild obsession with one another that can’t be tamed. But the truth about Juno’s real identity lurks, waiting to jump out and bite them. When it does, will their passion be put to the test? Or does an obsession like theirs overcome all?
