2019’s The River Twice is the first volume in Brenda W. Clough’s Edge to Center series.
It’s good to be the king! And if one lives in a purported republic with a dubious record of democratic transfer of power, it’s good to be the grand-daughter of the President. Calla Ang’s grandmother is Madame President of Jalanesia and (save for the tragic deaths of Calla’s parents when she was but a child) Calla’s life has so far been prosperous. Her future as the likely inheritor of her grand-mother’s position seems secure.
Her comfortable life is disrupted by the sudden appearance of a bewhiskered Englishman.
