THE PENDULUM IS SLOWING. THE GEARS ARE BREAKING DOWN.

These were the words of warning given to the last Keyholder of Eriaris. But since they came from the sinister Mistress of the Spektors, the Colonists didn't want to believe them. And why should they? Fortune, after all, has finally turned in their favor.

Against impossible odds, they survived the battle on Fenmire, took their worst enemy prisoner, and acquired a mysterious artifact that could silence the Mistress forever. Now, with a new mode of transportation and the aid of unexpected allies, the way is clear to find their missing friends and attempt to put everything to rights.

But then the ticking begins. New horrors appear. And the Colonists are thrown into a desperate race against the Sundering—a cruel affliction which threatens not only their beloved Keyholder, but every living soul. The harrowing adventure will take them deep into treacherous waters and forgotten corners of the world, fraught with new enemies and inconceivable dangers.

Meanwhile, clouds of war are gathering in the west as the insidious Blue Flames accelerate their plans. Politicians weave their webs. Darkness grows by the day. All things considered, Eriaris needs nothing short of a miracle. That, or a kid in an oversized top hat.

The Sundering Hours is the fourth book of the epic fantasy series The Riverfall Chronicles. For more information, visit jacquelynhagen.com.
