I adored this premise. Though I didn’t think much of the title before I started reading, at the beginning of chapter 2 my mind was both boggled and entranced. Literally, the main character, Oona, turns 19 on New Year’s in 1983 only to be pulled into New Year’s 2015, internally as much the teenager she was the day before but outwardly a wealthy woman in her 50s. Though shocked her assistant and her mother are there to assure her that this is, well, Oona’s normal and that the rest of her life will continue to be out of order. The good thing? Money is no issue. Due to the nature of her time jumps, other Oonas have been able to memorize stock market activity and carry it through the time jumps in order to make the right moves to make sure that every iteration of herself is immensely comfortable financially which will stifle the blow of being ripped from whatever life she has built on the last day of every year. Oona of yesteryear is usually good about leaving notes so that this Oona, the 19-year-old who’d never jumped through time before, as some sort of guidance, but going back and forth, enjoying another year of physical youth before being pushed back into her 40s proves to overwhelm her mind before she cares to seek guidance from her more experienced self. She gets into trouble, messing up her relationships and wanting men she can’t have, but the early drama is nothing compared to what she’s about to discover a couple years later. But in the mean time, Oona has to lay low and live, waiting to see where the following New Year will leave her.
