Introduction to a Temporal Universe

As always, it is refreshing to read a YA novel that isn't first-person. I take it that this is an introduction to a wider series as this first book lacks in the bit of adventure and concentrates more on character background and building the world.

Another good thing I noticed, split timelines were not used in this universe which itself is rare, it makes the time-travel more easier to understand for a wider audience. Good choice on that since we're also looking into a romance here.
