Responding to a tsunami on the tiny island of Guam should be a routine assignment for Dr. Anna Atao. From epidemics to earthquakes, she's treated patients in the most dangerous and remote places on earth. Except Anna hasn't been back to Guam since a tragedy there tore her life apart—and she left behind the man she loved. Seeing Nico brings back all the pain and joy of their time together, but Anna knows he'll never leave the island. And once her deployment ends, she plans to catch the first helicopter back to the mainland. Anna may be an expert in survival, but without Nico, can she ever truly heal?
