Day of the Horn (The Faun Quartet Book 1) by Chris J Edwards

A kidnapped princess. A reluctant mercenary. A shamed prince. Far in the west, isolated from the weary world beyond, lies the sylfolk kingdom of Céin Urthia - a woodland realm of ancient forests and sunlit meadows. But this kingdom cannot remain secluded forever; for Princess Dawn, heiress to the throne, has been mysteriously abducted. Not even her kidnapper, a mercenary battle-mage, knows who ordered it – or why. A fevered pursuit begins as the High King commands every servant of the crown to rescue her, even the disgraced and imprisoned Herace the Shamed. But even as he and his companions follow in wild pursuit, Princess Dawn herself must decide - does she even want to be saved? Meanwhile, powers beyond the sight of the court plot under cover of darkness - for not all wish to see the princess safely home... As civil war darkens the horizon, will Princess Dawn save her beloved home, or will unseen enemies win the day?
