Three things happened simultaneously. An abrupt sense of nausea washed over her, the light bulb went out, and her chair fell over backward.

“Ouch! Dammit!” Something thumped into Miriam’s side, doubling her over as she hit the ground and rolled over, pulling her arms in to protect her face. A racking spasm caught her by the gut, leaving her feeling desperately sick, and the arm of the chair came around and whacked her in the small of her back. Her knees were wet, and the lights were out. “Shit!” Her head was splitting, the heartbeat throb pounding like a jackhammer inside her skull, and her stomach was twisting. A sudden flash of fear: This can’t be a migraine. The onset is way too fast. Malignant hypertension?

The urge to vomit was strong, but after a moment it began to ebb. Miriam lay still for a minute, waiting for her stomach to come under control and the lights to come back on. Shit, am I having an aneurism? She gripped the locket so tightly that it threatened to dig a hole in her right fist. Carefully she tried to move her arms and legs: Everything seemed to be working and she managed a shallow sigh of relief. Finally, when she was sure her guts were going to be alright, she pushed herself up onto her knees and saw—

Trees.

Trees everywhere.

Trees inside her den.

Where did the walls go?

Afterward, she could never remember that next terrible minute. It was dark, of course, but not totally dark: She was in twilight on a forested slope, with beech and elm and other familiar trees looming ominously out of the twilight. The ground was dry, and her chair lay incongruously in a thicket of shrubbery not far from the base of a big maple tree. When she looked around, she could see no sign of her house, or the neighbouring apartments, or of the lights along the highway. Is there a total blackout? she wondered, confused. Did I sleepwalk or something?

She stumbled to her feet, her slippers treacherous on leaf mulch and dry grass stems. She shivered. It was cold—not quite winter-cold but too damned chilly to be wandering around in pants, a turtleneck, and bedroom slippers. And—

“Where the hell am I?” she asked the empty sky. “What the hell?”

Then the irony of her situation kicked in and she began to giggle, frightened and edgy and afraid she wouldn’t be able to stop. She did a twirl, in place, trying to see whatever there was to see. Sylvan idyll at nightfall, still-life with deranged dot-com refugee and brown office furniture. A gust of wind rattled the branches overhead, dislodging a chilly shower of fat drops: A couple landed on Miriam’s arms and face, making her shudder.

The air was fresh—too fresh. And there was none of the subliminal background hum of a big city, the noise that never completely died. It didn’t get this quiet even out in the country—and indeed, when she paused to listen, it wasn’t quiet; she could hear distant birdsong in the deepening twilight.

She took a deep breath, then another. Forced herself to thrust the hand with the locket into her hip pocket and let go of the thing. She patted it obsessively for a minute, whimpering slightly at the pain in her head. No holes, she thought vaguely. She’d once worn pants like this where her spare change had worn a hole in the pocket lining and eventually spilled on the ground, causing no end of a mess.

For some reason, the idea of losing possession of the locket filled her with a black terror.

She looked up. The first stars of evening were coming out, and the sky was almost clear of cloud. It was going to be a cold night.

“Item,” she muttered. “You are not at home. Ouch. You have a splitting headache and you don’t think you fell asleep in the chair, even though you were in it when you arrived here.” She looked around in wild surmise. She’d never been one for the novels Ben occasionally read, but she’d seen enough trashy TV serials to pick up the idea. Twilight Zone, Time Squad, programs like that. “Item: I don’t know where or when I am, but this ain’t home. Do I stay put and hope I automagically snap back into my own kitchen or… what? It was the locket, no two ways about it. Do I look at it again to go back?”

She fumbled into her pocket nervously. Her fingers wrapped around warm metal. She breathed more easily. “Right. Right.”

Just nerves, she thought. Alone in a forest at night—what lived here? Bears? Cougars? There could be anything here, anything at all. Be a fine joke if she went exploring and stepped on a rattler, wouldn’t it? Although in this weather… “I’d better go home,” she murmured to herself and was about to pull the locket out when she saw a flicker of light in the distance.

She was disoriented, tired, had just had a really bad day, and some cosmic trickster-god had dumped a magic amulet on her to see what she’d do with it. That was the only explanation, she reasoned afterward. A sane Miriam would have sat down and analysed her options, then assembled a plan of action. But it wasn’t a sane Miriam who saw those flickers of orange light and went crashing through the trees downhill toward them.

Lights. A jingle, as of chains. Thudding and hollow clonking noises—and low voices. She stumbled out into the sudden expanse of a trail—not a wide one, more of a hiking trail, the surface torn up and muddy. Lights! She stared at them, at the men on horseback coming down the trail toward her, the lantern held on a pole by the one in the lead. Dim light glinted off reflecting metal, helmet, and breastplate like something out of a museum. Someone called out something that sounded like: “Curl!” Look. He’s riding toward me, she thought dazedly. What’s that he’s—

Her guts liquid with absolute fright, she turned and ran. The flat crack of rifle fire sounded behind her, repeated short bursts firing into the night. Invisible fingers ripped at the branches overhead as Miriam heard voices raised in hue and cry behind her. Low branches scratched at her face as she ran, gasping and crying, uphill away from the path. More bangs, more gunshots—astonishingly few of them, but any at all was too many. She ran straight into a tree, fell back winded, brains rattling around inside her head like dried peas in a pod, then she pushed herself to her feet again faster than she’d have believed possible and stumbled on into the night, gasping for breath, praying for rescue.

Eventually she stopped. Somewhere along the way she’d lost her slippers. Her face and ribs felt bruised, her head was pounding, and she could barely breathe. But she couldn’t hear any sounds of pursuit. Her skin felt oddly tight, and everything was far too cold. As soon as she was no longer running, she doubled over and succumbed to a fit of racking coughs, prolonged by her desperate attempts to muffle them.

Her chest was on fire. Oh god, any god. Whoever put me here. I just want you to know that I hate you!

She stood up. Somewhere high overhead the wind sighed. Her skin itched with the fear of pursuit. I’ve got to get home, she realized. Now her skin crawled with another fear—fear that she might be wrong, that it wasn’t the locket at all, that it was something else she didn’t understand that had brought her here, that there was no way back and she’d be stranded—

When she flicked it open, the right-hand half of the locket crawled with light. Tiny specks of brilliance, not the phosphorescence of a watch dial or the bioluminescence of those plastic disposable flashlights that had become popular for a year or two, but an intense, bleached blue-white glare like a miniature star. Miriam panted, trying to let her mind drift into it, but after a minute she realized all she was achieving was giving herself a headache. “What did I do to make it work?” she mumbled, puzzled and frustrated and increasingly afraid. “If she could make it—”
