The book did a good job of portraying life proceeding WW2 in Berlin in the decade leading up to it, and following elsewhere in Europe from the perspective of a displaced female classical musician. Towards the end, the twist was unexpected, and I enjoyed being surprised though the whole of the end was sad. 

The time travel piece was weird because it was discussed as if it was an afterthought even tho it was central to the story. It not fleshed out or explained very well and had a lot of holes. The book itself was also very slow moving, and I struggled to connect with the characters. The perspective of each of the characters was fine in their own right, but when it came to their relationship, I just didn’t get it. Max went between clingy and oblivious, Hanna was super reactive, and neither one of them communicated about anything - he refused to give her information that would have made sense to, and she refused to ask questions. It felt like the only real interaction they had was about their physical relationship and listening to Hanna play. It just didn’t match their inner dialogue about each other.
