Lady of Basilikas - The Droseran Saga, #5

She's determined to prove this errant king unworthy. He's determined to prove her wrong. Under attack from without and within, Jherako teeters on the brink. Vaanvorn Thundred, suddenly in possession of a throne he never expected to inherit, will do anything to pull his kingdom from the edge, even if it means striking a marriage bargain with the formidable Faa'Cris. But a skycrawler opens Vorn's eyes to realities outside his world, and his limits are tested. Lady Valiriana has one goal when she is sent out from Deversoria: prove this Jherakan king, the one his people call the Errant, unworthy of an alliance with any Faa'Cris.
When she exchanges her freedom for that of another, Valiriana finds herself under house arrest-in the king's house. Determined to take advantage of her proximity, she delves into the depths of the king's character. What she finds turns her mission on its head. Vorn must decide: break a planet-wide Accord, risking his throne and life, or leave his country-his planet-vulnerable to threats far bigger than he ever imagined.
And Valiriana grapples with unpalatable truths as she discovers the king is anything but errant, while her heart, on the other hand, is a different story.
