I knew Callum would come for me. I leave the treacherous underworld behind and return to life with the man I love -- finally. But when I ask him to marry me, there's a heaviness in his silence. He admits that he's kept something from me...and he finally tells me his truth. A secret I wish he'd taken to the grave. A secret that changes everything. Callum had earned the respect and acceptance of everyone in my life, but then he destroys it in just the span of minutes. I'm not sure where this leaves us, but the situation only gets worse when Leviathan returns. The God of the Underworld says if I don't return to the underworld, the covenant will destroy the portal between our realms...and everyone I love will die.
