Winds of Chaos by Laura Brewer, Roland Brewer

Welcome to the training grounds of the Armies of Heaven. Born on a world full of dangerous creatures and agents of darkness, Alvinar and Rowan are rigorously trained to hunt and fight all manner of things to survive. Asked to lead a new settlement, far from aid, they throw themselves into the business of exploring and securing the area. Freya and Thor warn them trouble is on the horizon. When scouts find the remains of an ancient city, they go to explore; concerned at the presence of strange magic that feels – different. Several of the gods from Asgard come to investigate. An attempted invasion by portal stirs the strange magic in defense, but also destabilizes that magic and ripples are felt even in Asgard. Alvinar is changed by it and Freya takes him to Asgard. When a magical explosion in the ruins spreads chaos, even in Asgard, the very core of Rowan and Alvinar’s perception of who they are will be tried in its fire. Can they keep to the path of Light when Darkness seeks to sear their very souls?

Silver Fire (Chronicles of Asgard: Awakening, #2) by Laura Brewer, Roland Brewer

Rowan and Alvinari’s smooth routine is shattered by hordes of mordkii, larger and far better equipped than any they’ve ever seen, approach their borders. Rowan calls up every fighter and mage across the kingdom. Odin musters Asgard, but they are still horribly outnumbered.They block the advance, but when Alvinari breaks her spear, the replacement she’s given bursts into flame – and so does she. Her fire incinerates the enemies she’s facing – and almost consumes her friends. Hel has just begun to stir wars across the land and on the sea, unleashing demons. No place is safe.
