Natalie Chin-Williams might be a cranky professor of climatology who thinks the world is doomed, but she believes in lasting love...just not for herself. She has a long history of failed relationships, plus the men she dates inevitably want children and she doesn't.

She needs emotional support to get through the weekend, so she enlists the help of her friend Connor Douglas, the dependable family doctor.

The wedding reception goes south when a drunk aunt announces a family secret that sends Natalie reeling and shakes her faith in love. Luckily, she has her long-time friend to lean on—a man she somehow ends up kissing. But there's no way this could turn into anything lasting, is there? That's impossible for her, especially now...
