Scardown by Elizabeth Bear

Jenny Casey was not born for this mission. She was modified for it.

The year is 2062, and after years on the run, Jenny Casey is back in the Canadian armed forces. Those who were once her enemies are now her allies, and at fifty, she's been handpicked for the most important mission of her life - a mission for which her artificially reconstructed body is perfectly suited. With the earth capable of sustaining life for just another century, Jenny - as pilot of the starship Montreal - must discover brave new worlds. And with time running out, she must succeed where others have failed.

Now Jenny is caught in a desperate battle where old resentments become bitter betrayals and justice takes the cruelest forms of vengeance. With the help of a brilliant AI, an ex-crime lord, and the man she loves, Jenny may just get her chance to save the world. If it doesn't come to an end first . . .

Elizabeth Bear was born on the same day as Frodo and Bilbo Baggins, but in a different year. This, coupled with a childhood tendency toward reading the dictionary, doomed her early to penury, intransigence and the writing of speculative fiction.

She is a recipient of the John W. Campbell Award for Best New Writer and a Locus Award, and has been nominated for the BSFA, Philip K. Dick and Lambda awards. She lives in southern New England with a presumptuous cat and her hobbies include archery, guitar and the indiscriminate slaughter of defenseless houseplants.
