The Consequences of Fire (2016)

Publisher's blurb:

For months, stories have been filtering into Odill about strange events near the Parched Stretch, a small desert northwest of the city. First, creatures thought to exist only in mythology were seen by travelers when the desert more than doubled in size in a matter of days, only to shrink back to its original size after adventurers reportedly killed a blue dragon. Now, caravans passing near the desert have come under attack by brigands and not the typical bands of humans, orcs, or goblinoids either!
