The Impossible Lives of Greta Wells

By Andrew Sean Greer

(Ecco, $27)

The Impossible Lives of Greta Wells isn’t a reincarnation story. Not exactly. In 1985, after the death of her twin brother and a breakup with her boyfriend, Greta plunges into depression. Her doctor’s recommendation: electroshock therapy. When she wakes up after her first treatment, she’s been transported to 1918. After the next treatment: 1941. With each shock treatment, she jumps to another era in which the details of her life — and the people present in it — have changed. It’s a novel turn on a time-travel book that asks: If you could restart your life, would you? And what would you be willing to give up in order to regain someone you love?
