Given how long it is, the Frontiers Saga series has been remarkably solid. There are peaks and valleys in the books, but I guess that’s the nature of a many-book series. In a way, that’s part of the fun, following the story along the crescendos, waiting for the peaks to be reached. I am Justice is very much a peak: it’s really, really, good.
The previous book, Sanctuary, ended on quite the cliff-hanger, so I went straight into I am Justice, and it did not disappoint. There’s a bit of everything here: real feelings of peril, moral decisions where the outcomes don’t seem obvious, and some real emotional moments. While this series very occasionally falls into the trap of all good guys having plot-armour, some of that is torn away in I am Justice: introducing some situations of an absolute choice between two goods without “all of the above” being an option.
Without going into exactly what happens (writing a review of book 25ish of a series without wanting to even spoil the first one is getting a bit tricky), there’s several added strands of family-drama which have been set up through the previous books, and that come into play in this one. The politics of the universe also deepen a little bit, and become a bit more complex. That’s a strand I hope really continues in this series. The Frontiers Saga does have great space battles, and fun action, but when a book like this comes along and adds some proper world-and-character building on top of it… then this series goes from good to being great.
