The Education of Caroline by Jane Harvey-Berrick

Ten years after their first affair, Sebastian and Caroline meet again: this time in very different circumstances, against the background of the war in Afghanistan.
Carolina Maria Venzi was Mrs. Caroline Wilson. Now she has reinvented herself as Lee Venzi, freelance journalist and foreign correspondent. A chance meeting in Geneva sees the passionate madness of her taboo affair with a younger man rekindled.
Now Sebastian Hunter is a US Marine and unable to forget the first woman he ever loved. When Sebastian is sent to Afghanistan, Carolina is able to see close up the toll that war takes.

Can old passions be rekindled or are they both too wounded, too broken?
