Thank you to the publisher for a copy of this audiobook. This is the 2nd book of the series and can be read as a standalone but I do recommend you read Ghost first. The story is set in Switzerland, Serena who is a free spirit vegetarian physics. Her coworker, Henry, who she had a one night stand before she started her job is uptight and drives her nuts. This turns freaky Friday where Serena and Henry switches body. I love the story and how it goes from there. Their banter is funny and the dual POV and the narrators did a great job with expressing their emotions. I love that we see Jillian and Dan back in this story.
