2015’s The Mystic Marriage is the second volume in Heather Rose Jones’ Alpennia series.
Antuniet Chazillen has lost everything: her foolish brother has been executed for treason and her mother is dead by her own hand. Antuniet has been stripped of her aristocratic rank. Determined to restore the family honour, Antuniet flees Alpennia for Austria, there to use her alchemical skills to win back for her family the respect and position her brother cost it.
In Austria she finds a treasure of rare value, a treasure others are determined to wrest from her. She escapes from Vienna to Heidelberg, but her enemies are still close on her heels. She sees no choice but to trade her virtue for transportation to safety.
Which means returning to Alpennia…
