The Dowry Blade by Cherry Potts
Nine years after her clan was almost obliterated and her sister disappeared, Brede is unwillingly and unhappily living in the marshes. The sudden ending of a decade-long drought brings with it rumours that the rain was bought at the price of a King’s head and the Dowry Blade, the sword needed for such a sacrifice, is missing.
The arrival of Tegan, a wounded mercenary, brings even more questions. After a series of discoveries and revelations about the Dowry Blade, Tegan and Brede begin their journey to the capital in search of Brede’s sister.
