My name is Greta Forzane. Twenty-nine and a party girl would describe me. I was born in Chicago, of Scandinavian parents, but now I operate chiefly outside space and time — not in Heaven or Hell, if there are such places, but not in the cosmos or universe you know either.

I am not as romantically entrancing as the immortal film star who also bears my first name, but I have a rough-and-ready charm of my own. I need it, for my job is to nurse back to health and kid back to sanity Soldiers badly roughed up in the biggest war going. This war is the Change War, a war of time travelers — in fact, our private names for being in this war is being on the Big Time. Our Soldiers fight by going back to change the past, or even ahead to change the future, in ways to help our side win the final victory a billion or more years from now. A long killing business, believe me.

You don't know about the Change War, but it's influencing your lives all the time and maybe you've had hints of it without realizing.

Have you ever worried about your memory, because it doesn't seem to be bringing you exactly the same picture of the past from one day to the next? Have you ever been afraid that your personality was changing because of forces beyond your knowledge or control? Have you ever felt sure that sudden death was about to jump you from nowhere? Have you ever been scared of Ghosts — not the storybook kind, but the billions of beings who were once so real and strong it's hard to believe they'll just sleep harmlessly forever? Have you ever wondered about those things you may call devils or Demons — spirits able to range through all time ana space, through the hot hearts of stars and the cold skeleton of space between the galaxies? Have you ever thought that the whole universe might be a crazy, mixed-up dream? If you have, you've had hints of the Change War.

How I got recruited into the Change War, how it's conducted, what the two sides are, why you don't consciously know about it, what I really think about it — you'll learn in due course.

The place outside the cosmos where I and my pals do our nursing job I simply call the Place. A lot of my nursing consists of amusing and humanizing Soldiers fresh back from raids into time. In fact, my normal title is Entertainer and I've got my sffly side, as you'll find out.

My pals are two other gals and three guys from quite an assortment of times and places. We're a pretty good team, and with Sid bossing, we run a pretty good Recuperation Station, though we have our family troubles. But most of our troubles come slamming into the Place with the beat-up Soldiers, who've generally just been going through hell and want to raise some of their own. As a matter of fact, it was three newly arrived Soldiers who started this thing I'm going to tell you about, this thing that showed me so much about myself and everything.

When it started, I had been on the Big Time for a thousand sleeps and two thousand nightmares, and working in the Place for five hundred-one thousand. This two-nightmares routine every time you lay down your dizzy little head is rough, but you pretend to get used to it because being on the Big Time is supposed to be worth it.

The Place is midway in size and atmosphere between a large nightclub where the Entertainers sleep in and a small Zeppelin hangar decorated for a party, though a Zeppelin is one thing we haven't had yet. You go out of the Place, but not often if you have any sense and if you are an Entertainer like me, into the cold light of a morning filled with anything from the earlier dinosaurs to the later spacemen, who look strangely similar except for size.

Solely on doctor's orders, I have been on cosmic leave six times since coming to work at the Place, meaning I have had six brief vacations, if you care to call them that, for believe me they are busman's holidays, considering what goes on in the Place all the time. The last one I spent in Renaissance Rome, where I got a crush on Cesare Borgia, but I got over it. Vacations are for the birds, anyway, because they have to be fitted by the Spiders into serious operations of the Change War, and you can imagine how restful that makes them.

"See those Soldiers changing the past? You stick along with them. Don't go too far up front, though, but don't wander off either. Relax and enjoy yourself."

Ha! Now the kind of recuperation Soldiers get when they come to the Place is a horse of a far brighter color, simply dazzling by comparison. Entertainment is our business and we give them a bang-up time and send them staggering happily back into action, though once in a great while something may happen to throw a wee shadow on the party.

I am dead in some ways, but don't let that bother you — I am lively enough in others. If you met in the cosmos, you would be more apt to yak with me or try to pick me up than to ask a cop to do same or a father to douse me with holy water, unless you are one of those hard-boiled reformer types. But you are not likely to meet me in the cosmos, because (bar Basin Street and the Prater) 15th Century Italy and Augustan Rome — until they spoiled it — are my favorite (Ha!) vacation spots and, as I have said, I stick as close to the Place as I can. It is really the nicest Place in the whole Change World. (Crisis! I even think of it capitalized!)

Anyhoo, when this thing started, I was twiddling my thumbs on the couch nearest the piano and thinking it was too late to do my fingernails and whoever came in probably wouldn't notice them anyway.

The Place was jumpy like it always is on an approach and the gray velvet of the Void around us was curdled with the uneasy lights you see when you close your eyes in the dark.

Sid was tuning the Maintainers for the pickup and the right shoulder of his gold-worked gray doublet was streaked where he'd been wiping his face on it with quick ducks of his head.

Beauregard was leaning as close as he could over Sid's other shoulder, one white-trousered knee neatly indenting the rose plush of the control divan, and he wasn't missing a single flicker of Sid's old fingers on the dials; Beau's copilot besides piano player. Beau's face had that dead blank look it must have had when every double eagle he owned and more he didn't were riding on the next card to be turned in the gambling saloon on one of those wedding-cake Mississippi steamboats.

Doc was soused as usual, sitting at the bar with his top hat pushed back and his knitted shawl pulled around him, his wide eyes seeing whatever horrors a life in Nazi-occupied Czarist Russia can add to being a drunk Demon in the Change World.

Maud, who is the Old Girl, and Lili — the New Girl, of course — were telling the big heads of their identical pearl necklaces.

You might say that all us Entertainers were a bit edgy; being Demons doesn't automatically make us brave.

Then the red telltale on the Major Maintainer went out and the Door began to darken in the Void facing Sid and Beau, and I felt Change Winds blowing hard and my heart missed a couple of beats, and the next thing three Soldiers had stepped out of the cosmos and into the Place, their first three steps hitting the floor hard as they changed times and weights.

They were dressed as officers of hussars, as we'd been advised, and — praise the Bonny Dew! — I saw that the first of them was Erich, my own dear little commandant, the pride of the von Hohenwalds and the Terror of the Snakes. Behind him was some hard-faced Roman or other, and beside Reich and shouldering into him as they stamped forward was a new boy, blond, with a face like a Greek god who's just been touring a Christian hell.
