I was very looking forward to reading it and it did not disappoint! 
The whole story was very cute and got me in the mood for Christmas. My highlight definitely were the cat illustrations and the description of each cat at the beginning of each chapter. 
I also really enjoyed the characters. I liked the dynamic of Ben and Schwartz but also of Kara and Charity. I found the interactions with Ben and Kara very natural and I think they make a great match. 
In some extent I could relate to Ben's family problems and I'm not sure I would have been able to make the decision he did. 
Kara's story about her past was probably my least favourite part since it didn't feel natural to me and I also wasn't very invested in it. Overall a lovely and cute Christmas read I'm very happy I read!
