Wyrd Gods by Susana Imaginário

The God of Time wants to destroy Eternity. A mysterious immortal seeks vengeance. And a reclusive deity does what no god should ever do: she answers a prayer. As punishment, she is stripped of her powers and trapped in a mortal's body. Now a Wyrd – a fated god – she is haunted by the memories and thoughts of her host and must hide her true identity in order to survive in Niflheim, the rival Norse Underworld. There she discovers the afterlife is not quite what it used to be. Niflheim's new ruler threatens the precarious balance of a world overrun with outcast deities and mortals alike. To save her own sanity and find her way back to the stars, she must help the other Wyrd overcome their grievances to defeat this enemy, but those who would be her allies appear to have motives as hidden as her fragmented consciousness. And yet it seems the greatest threat to her freedom comes from within, and the prize it seeks is her immortal soul...

The Assassin of Grins and Secrets by K.E.Andrews

Once the infamous assassin who killed with a smile, Serein now waits for death in the fighting pits of the Harpy's Chest. When the crown prince of Sarddon, Rameses al-Amirmoez, seeks her out with an offer of freedom if she serves as his guard, she must decide whether to work for those who ravaged her homeland or die. Rameses wants to believe that the war his father started was justified, but he has heard rumors and seen a cruelty in his father that causes him to question everything he's been told. To find answers, he needs Serein. Uriah Stormheir, Captain of the Oyon's city guard, finds himself caught between his duty to the crown and his friendship with Rameses. His distrust for Rameses' new guard runs deep. As Uriah wrestles with guilt from his past, he must work alongside the dangerous assassin whose true motives are hidden underneath her scars and dark grins. In a land of hot sands and dying magic, Serein plays the game of secrets with Uriah and Rameses, knowing one wrong step could end her life. As the shadows of her past catch up with her, she has to choose between pursuing vengeance and protecting a secret only she knows.
