"I think I should have had a trade-in before we left. I'm about done in. Can't we call it a day?"

She tut-tutted, but touched a control and began spilling hot gas from the balloon over our heads. The steering vanes sticking out at our sides tilted, and we started a slow spiral to the ground.

We landed at the bottom of the bowl-my first experience with it, since all my other views of Venus had been from the air where it isn't so noticeable. I stood looking at it and scratching my head while Ember turned on the tent and turned off the balloon.

The Venusians use null fields for just about everything. Rather than try to cope with a technology that must stand up to the temperature and pressure extremes, they coat everything in a null field and let it go at that. The balloon on the cycle was nothing but a standard globular field with a discontinuity at the bottom for the air heater. The cycle body was protected with the same kind of field that Ember and I wore, the kind that follows the surface at a set distance. The tent was a hemispherical field with a fiat floor. '

It simplified a lot of things. Airlocks, for instance. What we did was to simply walk into the tent. Our suit fields vanished as they were absorbed into the tent field. To leave one need merely walk through the wall again, and the suit would form around you.

I plopped myself down on the floor and tried to turn my hand torch off. To my surprise, I found that it wasn't built to turn off. Ember turned on the campfire and noticed my puzzlement.

"Yes, it is wasteful," she conceded. "There's something in a Venusian that hates to turn out a light. You won't find a light switch on the entire planet. You may not believe this, but I was shocked silly a few years ago when I heard about light switches. The idea had never occurred to me. See what a provincial I am?"

That didn't sound like her. I searched her face for clues to what had brought on such a statement, but I could find nothing. She was sitting in front of the campfire with Malibu on her lap, preening her feathers.

I gestured at the fire, which was a beautifully executed holo of snapping, crackling logs with a heater concealed in the center of it.

"Isn't that an uncharacteristic touch? Why didn't you bring a fancy house, like the ones in town?"

"I like the fire. I don't like phony houses."

"Why not?"

She shrugged. She was thinking of other things. I tried another tack.

"Does your mother mind you going into the desert with strangers?"

She shot me a look I couldn't read.

"How should I know? I don't live with her. I'm emancipated. I think she's in Venusburg." I had obviously touched a tender area, so I went cautiously.

"Personality conflicts?"

She shrugged again, not wanting to get into it.

"No. Well, yes, in a way. She wouldn't emigrate from Venus.- I wanted to leave and she wanted to stay. Our interests didn't coincide. So we went our own ways. I'm working my way toward passage off-planet."

"How close are you?"

"Closer than you might think." She- seemed to be weighing something in her mind, sizing me up. I could hear the gears grind and the cash register bells cling as she studied my face. Then I felt 'the charm start up again, like the flicking of one of those nonexistent light switches.

"See, I'm as close as I've ever been to getting off Venus. In a few weeks, I'll be there. As soon as we get back with some blast jewels. Because you're going to adopt me."

I think I was getting used to her. I wasn't rocked by that, though it was nothing like what I had expected to hear. I had been thinking vaguely along the lines of blast jewels. She picks some up along with me, sells them, and buys a ticket off-planet, right?

That was silly, of course. She didn't need me to get blast jewels. She was the guide, not I, and it was her cycle. She could get as many jewels as she wanted, and probably already had. This scheme had to have something to do with me, personally, as I had known back in town and forgotten about. There was something she wanted from me.

"That's why you had to go with me? That's the fatal attraction? I don't understand."

"Your passport. I'm in love with your passport. On the blank labeled `citizenship' it says `Mars.' Under age it says, oh... about seventy-three." She was within a year, though I keep my appearance at about thirty.

"$o?"

"So, my dear Kiku, you are visiting a planet which is groping its way into the stone age. A medieval planet, Mr. Kiku, that sets the age of majority at thirteen-a capricious and arbitrary figure, as I'm sure you'll agree. The laws of this planet state that certain rights of free citizens are withheld from minor citizens. Among these are liberty, the pursuit of happiness, and the ability to get out of the goddam place!" She startled me with her fury, coming so hard on the heels of her usual amusing glibness. Her fists were clenched. Malibu, sitting in her lap, looked sadly up at his friend, then over to me.

She quickly brightened and bounced up to prepare dinner. She would not respond to my questions. The subject was closed for the day.

I was ready to turn back the next day. Have you ever had stiff legs? Probably not; if you go in for that sort of thing-heavy physical labor-you are probably one of those health nuts and keep yourself in shape. I wasn't in shape, and I thought I'd die. For a panicky moment I thought I was dying.

Luckily, Ember had anticipated it. She knew I was a desk jockey, and she knew how pitifully under-conditioned Martians tend to be. Added to the sedentary life styles of most modern people, we Martians come off even worse than the majority because Mars' gravity never gives us much of a challenge no matter how hard we try. My leg muscles were like soft noodles.

She gave me an old-fashioned massage and a newfangled injection that killed off the accumulated poisons. In an hour I began to take a flickering interest in the trip. So she loaded me onto the cycle and we started off on another leg of the journey.

There's no way to measure the passage of time. The sun gets flatter and wider, but it's much too slow to see. Sometime that day we passed a tributary of the Reynolds Wrap River. It showed up as a bright line in my right eye, as a crusted, sluggish semi-glacier in my left. Molten aluminum, I was told. Malibu knew what it was, and barked plaintively for us to stop so he could go for a slide. Ember wouldn't let him.

You can't get lost on Venus, not if you can still see. The river had been visible since we left Prosperity, though I hadn't known what it was. We could still see the town behind us and the mountain range in front of us and even the desert. It was a little ways up the slope of the bowl. Ember said that meant it was still about three -days' journey away from us. It takes practice to judge distance. Ember kept trying to point out Venusburg, which was several thousand kilometers behind us. She said it was easily visible as a tiny point on a clear day. I never spotted it.

We talked a lot as we pedaled. There wash nothing else to do and, besides, she was fun to talk to. She told me more of her plan for getting off Venus and filled my head with her naive ideas of what other planets were like.

It was a subtle selling campaign. We started off with her being the advocate for her crazy plan. At some point it evolved into an assumption. She took it as settled that I would adopt her and take her to Mars with me. I half believed it myself.

On the fourth day I began to notice that the bowl was getting higher in front of us. I didn't know what was causing it until Ember called a halt and we hung there in the air. We were facing a solid line of rock that sloped gradually upward to a point about fifty meters higher than we were.

"What's the matter?" I asked, glad of the rest.
