Divine Rivals by Rebecca Ross

All eighteen-year-old Iris Winnow wants to do is hold her family together. With a brother on the frontline forced to fight on behalf of the Gods now missing from the frontline and a mother drowning her sorrows, Iris’s best bet is winning the columnist promotion at the Oath Gazette. But when Iris’s letters to her brother fall into the wrong hands – that of the handsome but cold Roman Kitt, her rival at the paper – an unlikely magical connection forms. Expelled into the middle of a mystical war, magical typewriters in tow, can their bond withstand the fight for the fate of mankind and, most importantly, love?
