Heartstrings & Hormones

You have a secret—one that not even your best friends know. Every time your heart rate gets too high—whether it’s from anger, excitement, fear, or even just being a little too happy—you transform into a girl. The change is sudden, unavoidable, and lasts until you go to sleep. No doctor can explain it, no treatment can stop it, and you’ve learned to live with it… sort of. Your parents cover for you by claiming your “twin sister” is homeschooled and doesn’t go out much. Most people buy it. But juggling two identities while trying to survive high school isn’t easy—especially when your tomboy best friend makes your heart race just by smiling at you, your genius inventor friend is getting suspicious, and your conspiracy-obsessed buddy thinks everyone is hiding something. One wrong moment… and your whole world could change.
