ALL OUR YESTERDAYS

Time travel done right.

Narrator Em and her boyfriend, Finn, escape from their totalitarian future, time traveling back four years to commit a heart-wrenching assassination of a loved one in order to prevent time travel from being invented and the future from turning so wrong. The future’s hinted-at horrors are threatening but expertly backgrounded, avoiding dystopia-fatigue. The clever, accessible time-space treatment isn’t weighed down by jargon. Em and Finn’s proactive mission means the characters are the hunters instead of the frequently seen on-the-run teen protagonists. The other side of the storyline, taking place in the past that Em and Finn travel to and starring their past selves, is narrated by Marina (Em, in this timeline) and involves her brilliant yet interpersonally challenged best friend (and crush) James and his friend Finn, who annoys Marina, as they deal with a tragedy in James’ family. The believable, complex relationships among the three characters of each respective time and in the blended area of shared time add a surprise: A plot ostensibly about assassination is rooted firmly in different shades of love. Perhaps richest is the affection Em feels for Marina—a standout compared to the truckloads of books about girls who only learn to appreciate themselves through their love interests’ eyes.

Powerful emotional relationships and tight plotting in this debut mark Terrill as an author to watch.
