Mary-Anne has moved on, grown since the disastrous and passionate days of the Haiti earthquake response. Now, with World Aid Corps, based in Dolo Ado, Ethiopia, she struggles to balance life, love, and career following the opening of yet another new refugee camp at Bur Amina. Will the heart-wrenching plight of an endless supply of refugees stretch her to the breaking point? Or will she rise beyond the challenges? And what will become of Jean-Philippe? Will prolonged separation cause their hearts to grow fonder? Or will she find comfort in the arms of the mysterious, brooding Jonathon Langstrom? Will she take a job at HQ? Or will she continue to answer the humanitarian call from a dusty refugee camp on the border of Somalia? In the end, just how close will Mary-Anne come to crossing the lines from missionary to mercenary, and from mystic to misfit?
