Greythorne by Crystal Smith

Princess Aurelia’s life is turned upside down when the kingdom she thought she saved turns to ruin, a loved one is tragically killed in a shipwreck, and her home country refuses to respect her brother’s legitimate claim to the throne. With no place left to call her own, Aurelia returns to Greythorne Manor—her best friend’s family mansion—only to get swept up in a coup d’état on the night of her brother’s coronation.

With everyone turned against her and enemies closing in on all sides, Aurelia has nothing left to lose in a mad fight to protect the only people she has left—her family. But in her darkest moments when all seems grim, will Aurelia find a spark of hope from a love she thought long lost?
