The Burning, by Kathryn Lasky, was published in 2004 by Scholastic. It is the sequel to The Shattering.
The Burning is the last of the six-book fleck/Pure Ones/St. Aggie’s arc before Lasky takes the series into a different direction. As a last book, it wraps everything up as it’s supposed to: there’s tension and uncertainty to ramp the tension up before the final battle, the villains are defeated, and great acts of bravery are performed by multiple characters.
Yet there is still much left to be desired with this “closing” of the first Soren arc (for he comes back later on in the series). The time jumps are bothersome, leaving great swathes of character’s actions to be explained in commentary or as an afterthought later on. This includes Gylfie and Otulissa leaving the Glauxian Brother’s Retreat, Soren’s insistence on not teaching the St. Aggie’s owls to fight, and Gylfie’s appeal to the Northern owls parliament. In fact, Gylfie’s entire courageous arc, where she escapes from pirates and brings an army to help out the Guardians at just the right moment, is entirely overshadowed by a brand-new viewpoint character, and her most amazing moment is never even seen, though we get some of its effect later on when she meets back up with Soren at the battle.
In addition to those odd jumps, Lasky decides to have the battle between Kludd and Soren end in a rather strange way, though at least that decision makes more sense than the random jumps in time. We get a fight between Soren and his brother, but the end result is strangely anticlimactic and unsatisfying. In fact, it seems to have been done purposefully to preserve Soren’s purity than for any other reason. Or perhaps it was to show how different Soren is from his brother—though that, of course, isn’t a necessary distinction to make since we already know that Soren is far and away the better owl.
Anyway, despite my grumblings, I still thought The Burning was a good end. It wraps up the Pure Ones arc very neatly, and it leaves room for some more growth to the series with the very brief reveal at the end with Nyra. The missteps and the strange choices are probably due to the fact that the last couple of books were published in the same year, so Lasky likely didn’t have a lot of time to really think about the choices she was making.
