HOW TO SAVE YOUR OWN LIFE
by Erica Jong

No longer afraid of flying, today's everywoman divorces her shrink-husband, is duped by Hollywood sharks and finds true love with a younger man. Where does Erica end and Isadora take over? No matter; it's shameless, sex-saturated and a joy. (Holt, Rinehart & Winston, $8.95)

LANCELOT
by Walker Percy

No knight has ever been able to handle his wife's adultery with much finesse, and Lancelot Lamar of New Orleans botches it too. The last of the great Southern novelists hates today's world, but his sense of humor and wry, sly observations are rich as ever. (Farrar, Straus & Giroux, $8.95)

CHANGING
by Liv Ullmann

The Norwegian actress muses about her long affair with director Ingmar Bergman and her non-affair with Kissinger, but this is less a movie gossip autobiography than scenes from the nerve-wracking life of a thoughtful woman. (Knopf, $8.95)

CONDOMINIUM
by John D. MacDonald

Where was Travis McGee when the wheeler-dealers put up this shoddy building? The consummate mystery writer, MacDonald turned this one out for disaster novel addicts, Who will love the Florida hurricane that wipes out a horde of unpleasant old folks. (Lippincott, $10)

THE FAN
by Bob Randall

A successful playwright (6 Rms Riv Vu, The Magic Show), Randall gives his first novel a Broadway backdrop: an aging Broadway star tries a stage comeback while a psycho admirer stalks her. Make sure the doors are locked before you start to read. (Random House, $7.95)

FALCONER
by John Cheever

This tale of a suburban man who gets 10 years for killing his brother manages all the sordid prison clichés you've ever heard—but in elegant prose. The cool, detached Cheever may drive a few readers stir crazy with his remote symbolism. (Knopf, $7.95)

OLIVER'S STORY
by Erich Segal

Love Story meant never having to say he was sorry, so Segal returns with an even more naive and utterly silly sequel. What can you say about an author who wrote a novel that sold over nine million copies? (Harper & Row, $7.95)
