Ruby & Onyx by Summer Grace

Trapped in the remote village of Carcera, Radya dreamed of an impossible life:
A life outside of the magical barrier. A life of love and adventure. A life liberated from the menacing red eyes haunting her nightmares.
Those delusions were merely a dream, until those red eyes turned corporeal and revealed a fate foretold from ages past.
Forced to reckon with an arranged marriage to the snarky and fickle Prince of Mendacia, who grates on her nerves as often as he quickens her pulse, Radya must navigate an unfamiliar world of magic, lies, and deception. The closer she gets to the truth, the more people get hurt. Each revelation comes at cost, threatening to ignite a war between Kingdoms and lovers.

Will Radya choose this new life, despite the profound repercussions? Or will she follow her dreams, which connect her to yet another life unknown?
