Eris by Alessa Thorn

Eris, the goddess of chaos, has given up hope of ever breaking free of the curse that’s haunted her for centuries—until the Fates offer her an unexpected chance at redemption.

Enter Enzo Silviano, a charming bartender and failed therapist with a hidden lineage going back to ancient Troy. When Eris discovers he’s the key to lifting her curse, she does the one thing gods do best and traps him into a deal he can’t refuse.
Their mission from the Fates? Return the legendary Palladium to its rightful place, retracing the steps of Aeneas’s legendary journey to Rome, and don’t go mad or get eaten by monsters on the way.
As they sail the Mediterranean, they will have to face mythical creatures, their dark pasts, and their growing feelings for each other. Eris will learn that there are some things more important than lifting her curse…and Enzo will realize that falling in love with a goddess will be the most dangerous thing he could ever do.
