The Impossible Lives of Greta Wells by Andrew Sean Greer, is a novel for those who enjoy time travel.

Greta is deeply depressed in 1985 after the death of her twin brother and departure of her longtime lover. She consents to undergo an experimental treatment similar to electric shock which sends her into other lives in other times. With a little suspension of disbelief it is possible to travel through time with Greta as she inhabits each of these three lives in alternating sequences.

A fun and fascinating portrait of life in 1918, 1941 and 1985. I enjoyed the novel, but never cared enough for any of the characters to get deeply invested. It was a little hard to keep track of their different personalities as they all kept changing through time. An interesting, if somewhat forgettable, novel.
