Brian Caldwell has it all?college stardom, effortless charm, and a girlfriend who should be perfect. Until she isn't. When Ashley ends their relationship and demands space to "see other people," Brian's wounded pride leads him to a petty act of revenge: stealing her prized, eight-hundred-dollar bottle of Parfum d'Obsession Noire.

He never expects thecrystal to shatter at his feet.

One accidental dousinglater, the rare, black-market fragrance?rumored to manifest a person's deepest,most denied desires?begins its merciless work. Brian's six-foot-two jock frameshrinks and reshapes into something impossible: five feet of exaggerated,hyper-feminine curves, platinum waves cascading past a heart-shaped ass,bee-stung lips, and breasts so large they defy physics. His wardrobe morphswith him?boxers to lace, sweatpants to a skin-tight dress, sneakers topunishing stilettos. Between his legs, the final, agonizingly erotic changeseals his new identity.

He is no longer Brian.

He is Betty.

Ashley knows exactlywhat the perfume does. She also knows Betty is what Brian secretly craved allalong, even if he never admitted it to himself. One squirt lasts a week. Awhole bottle? Years.

What begins as horrorquickly spirals into dark, intoxicating liberation. Betty discovers power shenever had as Brian: the ability to reduce his former best friend to a trembling,leaking mess with nothing more than a slow unzip under a lecture-hall desk. Oneby one, the boys who once called Brian "bro" fall under her spell?helpless,humiliated, and helplessly addicted.

In the mirror, Bettysmiles at the reflection Brian would have hated... and envied.

Revenge, it turns out,smells like jasmine, amber, and total surrender.

A sizzling erotictransformation tale of spite, self-discovery, and seductive payback. Somedesires are too deep to deny?and once unleashed, they never go back in thebottle.
