TRAVELING BY MYSTICAL ifrit hound sounded cool in theory and entirely plausible, since he was the size of a smallish horse. But horses were trained to carry humans, while ifrit hounds were not. It took every muscle in my body to stay on his back. He ran through the streets, leaping over obstructions, dodging occasional cars, and panicking horses.

Three minutes into our race Curran drew even with us, a huge gray beast that was neither lion nor human, designed specifically for running. That was Curran’s special power—he molded his body at will to whatever purpose suited him. He’d chased me down more than once in this shape. A few moments later Derek caught up with us. He was still in his human form. Above a shadow swooped across the stars and pulled ahead. The ifrit was fast, but beating a winged horse required a whole other kind of fast. A blue spark flared, illuminating the horse and rider. Bahir must’ve carried a feylantern. He flew above us like a beacon. Hopefully Mahon, Luther, and the knights would see him.

Magic scoured me. We had crossed the invisible boundary into Unicorn Lane. Of course. Why would it be anywhere else? Unicorn Lane cut through the center of the city, as if some enormous invisible enemy drew a dagger and stabbed deep into the very heart of downtown Atlanta, and now magic geysered out from the wound. Normal rules didn’t apply here. This was a place of predators and prey where plants attacked you, moss was poisonous, and glowing eyes tracked your every move.

The magic churned and boiled around me as we darted among the dark ruins of once-mighty skyscrapers. Adib turned left, leaped over the remnants of a gutted building, and shot out of Unicorn Lane running northwest along the crumbling Colier Road. Well, that was unexpected.

Colier Road, a simple two-lane street, once ran through residential neighborhoods, but as Unicorn Lane grew, it swallowed the road’s southern end, and Colier became a street that led nowhere. During magic waves, creatures hiding in Unicorn Lane ventured out in search of meat and blood, and the road nicely funneled them directly to their prey asleep in beautiful colonial houses. Anyone with a crumb of brains moved, and over the years, the residential neighborhoods once lining Colier became deserted. Abandoned houses tracked our progress with dark windows.

The ifrit kept running. A large ruin loomed on the left. An old sign flashed by, bent and grimy. PIEDMONT HOSPITAL. That’s right. The original hospital complex stood so close to Unicorn Lane that part of it had collapsed in the Shift. Not realizing the full impact of Unicorn Lane’s existence, the city had rebuilt it a few miles down the road, but then, as the residential neighborhoods withered, so did the hospital, and if they had built it with that algae, the first flare would’ve finished it.
