The Fomorian Wyrmriders Books in Order

Escaped wyrms threaten Fomoria and New Orleans, but Joni Campbell alone can hear their fear of something worse. To prevent destruction, she must tame the creatures and keep the merfolk from killing the very beings she needs.

A defeated enemy returns with an alliance of time-traveling ghost pirates and a fleet of spectral ships. Joni and the wyrmriders must discover what the raiders want and stop them before their violence spreads across the world.

Joni and her newly trained wyrmriders face fast-moving zombie sharks whose bites may spread an underwater catastrophe. Stopping the creatures is only part of the problem: she must find the magic-worker raising them before more appear.

A new generation of wyrms requires new riders, but resistance to Joni's leadership threatens the training effort. As rebellion grows within Fomoria, she must prevent rivals from overthrowing her and launching a campaign to dominate the seas.
