I have a love-hate relationship with  alternating timelines however I don’t know how I feel about the timeline in this because none of it felt distinct from the present or the past like nothing in their life has changed from the past events. Usually in pay and present timelines there is something that we don’t know that happened in the past that we find out as the timelines get closer together which did happen but it didn’t work because what happened was lackluster because I felt like I already knew. It didn’t take away from the plot or the book at all but I just found it unnecessary.
