The King's Captive (Gate of Myth and Power, #1)

by K.M. Shea

Yes, I should protect my new pet, but what I had planned went beyond what was necessary. Using it would be impulsive, foolish, and brash. If any of my friends knew, they’d discreetly question my sanity. And yet… Magic hummed around me, pleased with the idea. Even the shackle that held back a major portion of my power couldn’t hide the musical chord magic produced at the thought. All supernaturals wielded magic differently. Humans—magic’s absolute favorites—didn’t need anything. Wizards could pull wild magic from the air and filter it through their blood into a usable, elemental form. Fae used magical tools and artifacts to bend wild magic to their will. Elves were somewhat similar in that we worked best if using an artifact or tool, but it wasn’t fully necessary. The check to our power, however, was emotions. Our mood and emotion drastically affected our ability to wield magic.

so weird, we're the favorites? That's new, maybe ease vs. mega power or something.
