Goddess (Calypso Book 2)

Two weeks ago, Callie Ingram was just another high school senior with her sights on a swimming scholarship. Now, she’s the resurrected leader of the Vikings, balancing her classes with learning mythological history—and sparring sessions with her gorgeous demigod boyfriend, Liam Hale.
 
When Zeus returns to collect the favor she owes him, Callie is tasked with uniting the warring Viking clans and leading them into battle against Gaia’s frost giants. If she fails, everything she risked her life for will be destroyed…and her best friend will die. But one teenage girl rallying all of the vengeful clans won’t be easy. And things only get more complicated when a new prophecy puts her future with Liam at risk. Now, Callie will not only have to win the battle, but she’ll have to take the fate of her heart into her own hands.
