My difficulty was that it reminded me so much of Me Before You that it was hard to not compare and if you compare the two well this one isn't even close. The writing style at times was a bit juvenile and the story at times far-fetched, but all in all it was a good read and good story. Was kind of disappointed with the way Annie's mother's tale wrapped up it was just kind of like the story focused on her and Polly evenly throughout most of the book and suddenly she was kind of dropped and then picked up again and quickly summed up.
Very poignant author's note at the end.
Anyone who has a habit of thumbing to the back to learn about the author I'd recommend saving the author's note to the end where it is because it could be a spoiler for the book.
