Her head lolls forward, her hands slack on the reins.

“Hey, princess. I was wondering—who inherits the throne once you fall asleep?” I absolutely do not care about the inheritance laws of a fairy tale kingdom I’m about to zap myself out of, but I figure it’s the kind of thing a princess might care about.

Her head jerks upright. “What? Oh. I believe the crown will pass to my Uncle Charles, as I have no brothers or sisters.” I wonder exactly when the exclamation points left her sentences, and wish absurdly that I could restore them.

“I don’t have any siblings either,” I offer, sounding like an extremely boring first date. “I always wanted a little sister, but…” Mom and Dad said they only ever wanted one kid, but I’m pretty sure they’re lying. I think they wanted to spare me from a younger sibling who would inevitably outgrow me, a 2.0 version of myself with all the bugs and fatalities worked out, but honestly I wish they’d had a second kid to pour their hearts into. “Anyway. At least I had Charm.”

“Charm?” Primrose says it like a noun rather than a name.

“Haven’t I mentioned her? Here.” I fish my phone from my hoodie and power it on (18%). I curve my arm around the princess so she can see my lock screen: Charm simultaneously blowing me a kiss and flipping me off. It’s summer and she’s wearing a black tank top to show off what she refers to as her “lady-killers” (biceps) and her “job-killers” (tattoos).

Primrose looks at Charm’s face for a length of time that confirms my suspicions about her. She straightens in the saddle, shutting her mouth with an almost audible click of teeth. “A friend of yours?”

“The very best.” The only, really. “We met in second grade when she decked a kid for asking if my parents let me pick out my own casket. She got sent to the principal’s office and I played sick so I could go sit with her in the hall. She’s stuck with me ever since, despite my … curse.” Or, if I’m being honest with myself, because of it.

Charm’s parents already had three kids when they saw a ’90s Frontline special about homeless youth in Russia. They “rescued” Charm from a St. Petersburg orphanage six months later and never let her forget it. Every time she misbehaved they told her to be grateful she wasn’t begging on the streets; every Christmas her dad jokes that they already got her the American Dream, so what else could she want?

It gave Charm a gigantic chip on her shoulder, biweekly counseling sessions at school, and a lifelong desire to be a hero. To be the one doing the saving, rather than being saved. There’s a reason she has a tattoo on her shoulder of an adopted foreign baby who grew up to save the world again and again.

I figure the GRM made me the ultimate challenge, an unrescuable damsel. Charm used to spend hours and hours with her brother’s chemistry set and a stack of Encyclopedia Britannicas—as if a third grader was going to discover the cure to an incurable genetic disorder—until she grew out of it and gave up. At least it wasn’t a complete waste of time: she blew the top off the science section of the ACT and got her pick of internships at fancy biotech companies when she graduated. (I was pushing for this tiny start-up that was trying to clone organs on the cheap, but she went with Pfizer, an objectively terrible pharmaceutical giant, for reasons I genuinely cannot fathom).
