After Caroline by Kay Hooper
Paperback, no page numbers but I'd guess around 350, Good condition - cover has a slightly bent crease. Sold new for $4.99
Two women who look enough alike to be twins. Both involved in car wrecks at the same time.
One survives. One doesn't.
Now, plagued by a bewildering connection to a woman she never knew, driven by an urgent compulsion she doesn't understand, Joanna Flynn travels three thousand miles across the country to the picturesque town where Caroline McKenna lived - and mysteriously died. There Joanna will run into a solid wall of suspicion as she searches for the truth: Was Caroline's death an accident? or was she the target of a killer willing to kill again?
