Wishborne

Be careful what you wish for….
When amateur footage of a mage performing a spell goes viral back home, American Pyromancer Blayze Martinez hops on a plane to London. If the world is about to discover the existence of magic, he wants to be as far from the epicenter of that nightmare as possible.
Shy, enormous hunk Dane Peterson can amplify others' emotions, an ability that takes practice to control. Though he and Blayze come from different worlds, they hit it off. But their casual evening goes sideways when a shared wish at a mage party ends with each of them inside the other's body—literally.
The body swap is one thing, but the magical skill swap is a potential disaster. While Dane and Blayze work out how to reverse the wish, they have to keep their powers under wraps or risk dooming all of magekind.
