Deephearth (2014)

From publisher blurb:

Where the waves of the Endless Sea lazily roll into a rocky inlet lies the small svirfneblin fishing village of Deephearth. Hidden in a seldom used tunnel network, the svirfneblins of Deephearth lead quiet lives unnoticed by the many lurking dangers of the Ebon Realm. Recently an earthquake blocked the mouth of the inlet where Deephearth is sitting, but the village itself escaped the event damaged. However, lately svirfneblins have gone missing. At first fishing boats disappeared without a trace, but now even villagers have disappeared from their own beds! The villagers look to their leaders for guidance, but the council is unable to act, as one of their own is among the missing.
