Emma nodded, and the Twins exchanged a look and shared a secret giggle that turned Emma’s stomach. Then Gabby steered the car out of the parking lot and made a left at the light. Lili tapped away on her iPhone. Emma could just make out the Twitter icon on the little screen. She leaned forward, dying for a peek. Was Lili writing under her secret Twitter name? Was she sending a secret missive to Gabby?

Lili cocked her head, noticing Emma. Emma snapped her head away, pretending she wasn’t looking. Lili covered the screen with her hand and smirked. Emma pulled out her phone to check, but nothing new was posted.

Gabby merged onto the freeway, snaking around cars and nearly cutting off a fast-moving milk truck. “So, Sutton. Excited for tomorrow night?” She swiveled around and glanced at Emma, taking her eyes off the road.

“Gabby!” Emma screamed, gesturing toward the highway with her phone. Was Gabby even allowed to be behind the wheel? Could people with epilepsy get driver’s licenses?

One corner of Gabby’s lips lifted into a smile. She still didn’t turn around. “But, Sutton, I thought you liked to live on the edge!”

“Whoo, whoo!” Lili said in a high-pitched voice, her fingers flying over the iPhone’s keyboard.

More cars honked at the SUV. Sweat began to bead on the back of Emma’s neck. She placed a hand on Gabby’s shoulder as a pickup truck swerved out of her way. “Gabby, please!”

Finally, as Gabby was about to have a head-on collision with an oncoming Jeep Cherokee, she calmly faced forward and wrenched the SUV back into the far lane like they’d never been in peril at all. “We’re really excited for Homecoming, Sutton,” she said, picking up on the previous conversation as though nothing was amiss. “It’s a big night for us. You’re going to die when you see us!”

Emma flinched. “Excuse me?” She grabbed the door handle, wishing she could jump out of the car.

Lili giggled. “Our costumes are amazing.”

“God, what did you think we meant?” Gabby asked, snickering. The girls exchanged another glance, as though they knew how much they were freaking Emma out.

Just then, Gabby took the next exit and turned into a dingy lot. A sign on the chain-link fence read TUCSON PD IMPOUND. As they pulled in, a beefy man with a shaved head emerged from a small, nut-colored building and motioned for Gabby to roll down the window.

As soon as the car slowed, Emma unlocked the passenger door and jumped out.

“Sutton!” Gabby called. “What the hell?”

“I can take it from here!” Emma yelled back, relieved to be standing next to the worker, who had ham-sized arm muscles and a menacing tattoo peeking out from under his collar. “But thanks, guys! I really appreciate the ride!”
