Hyena Queen. The Legend of Synthia Rowley, #1

My name is Synthia Rowley, and so far I really suck at saving the world.  I'm a latent shifter, a human that randomly became a hyena Queen. Crazy, right? You have no idea. When I turned twenty-five some magical chastity belt that had been completely blocking my sex drive snapped. One minute I was the ultimate shy science dork, the next I had curves that kill and a libido that won't quit.   Good thing, 'cause I'm supposed to have four husbands.  Yep, four.
I'm destined to marry them all and they were all born to love me and only me. My own little harem. Here comes the really insane part. My husbands? The four men that I'll be mated to for the rest of my life? They were born female and my pheromones will turn them into men. You heard me right, my hyena Queen pheromones will literally change my mates from women, into hulked out sexy studs. But if I don't find and transform my mates, and soon, my world and everyone in it will be slaughtered by demons from a different dimension.  Good times.
