Dru Pagliassotti Books in Order

Metal-winged courier Taya moves freely through Ondinium's rigid castes until a daring rescue entangles her with the privileged Forlore brothers. Their dangerous secrets draw her into murder and political intrigue within a city governed by its vast mechanical engine.

An ancient seal breaks beneath a California university, releasing beings from beyond heaven and hell. A retired priest and an ailing magician seek help from mysterious allies while students and staff confront forces that overturn their understanding of faith and reality.

Taya accompanies her husband Cristof on a diplomatic mission to investigate another nation's airship technology. As Ondinium approaches war, a crash and a murder force her to navigate international danger and the demands of a government that treats people as expendable.

A peace mission collapses when Taya and Ondinium's diplomats are framed for regicide and trapped aboard a damaged ship. With enemy armies advancing, she and Cristof fight to protect their homeland from a weapon threatening its mechanical heart.
