Dragon's Gift: The Valkyrie, book 5: Master of MagicLinsey Hall2018

It’s kill or be killed when fighting the gods. Life is full of good and bad. Good — I’ve rescued my sister. Bad? — We’re being hunted by the Rebel Gods, powerful beings who are determined to kill us—and cause the end of days. So yeah, that’s real bad. It’s up to me to find them and kill them before they destroy life as we know it. To do that, I have to finish my transition to DragonGod and master my magic. It’ll require a deadly adventure through the realms of myth, but with help from my sisters and the sexy war god Cade, I might have a chance. To succeed, we’ll have to unite old and new friends in the battle of a lifetime.
