Hall of Smoke by expédition Long, H. M. NEUF

Hessa is an Eangi: a warrior priestess of the Goddess of War, with the power to turn an enemys bones to dust with a scream. Banished for disobeying her goddesss command to murder a traveller, she prays for forgiveness alone on a mountainside. 

While she is gone, raiders raze her village and obliterate the Eangi priesthood. Grieving and alone, Hessa — the last Eangi — must find the traveller and atone for her weakness and secure her place with her loved ones in the High Halls. As clans from the north and legionaries from the south tear through her homeland, slaughtering everyone in their path Hessa strives to win back her goddess favour. 

Beset by zealot soldiers, deceitful gods, and newly-awakened demons at every turn, Hessa burns her path towards redemption and revenge. But her journey reveals a harrowing truth: the gods are dying and the High Halls of the afterlife are fading. Soon Hessas trust in her goddess weakens with every unheeded prayer. 

Thrust into a battle between the gods of the Old World and the New, Hessa realises there is far more on the line than securing a life beyond her own death. Bigger, older powers slumber beneath the surface of her world. And theyre about to wake up.
