Mouth to Mouth by Tessa Bailey

A man with a prison record has no place around a fresh faced college student. Tell that to Rory Prince. He should stay the hell away from Olive Cunningham. There’s one small problem, though. She won’t stop almost getting killed—and with this too-smart, too-sweet girl holding his heart in her hands, Rory is powerless to do anything but keep saving her.
Homeschooled from a young age, Olive is now out on her own and discovering the world, one milkshake flavor at a time. Until recently, she has experienced life through books. She’s walked in a million sets of shoes while flipping pages—enough to know that Rory gives her once-in-a-lifetime feelings. If only he would stop trying to protect her…from himself.
