True Hero  by Cris Galdamez:
 
A Touch of Darkness meets Daughter of No Worlds in this swashbuckling Greek mythology-inspired NA Romantic Fantasy!

Her demise is only the beginning.
I was once a powerful Olympian Goddess, but now I’m barely a mortal, punished to wander this strange land. I gave up on ever seeing my home or loved ones again. I gave up on happiness.
I merely survive.
But why does my skin tingle when a local hunter sets his silver eyes on me? What is this thumping in my heart when I hear rumours of a long-forgotten way to gain access to Olympus? How can I tell myth from truth?
One thing is
I will stop at nothing to go back home.
And so, I fight. Guided by warriors and centaurs from legend, I train to become a hero deserving of the grace of the Gods.
Everything is going according to plan until my true identity is unveiled by who turns out to be no other than the infamous God of the Underworld. Blades sing, sparks fly, but the line between duties and wants is one that cannot be erased.
And I’ve already lost too much.
When the fate of the realms is put on the line, I will have to confront the secrets of my past and embrace my fate...
But will I?

True Hero is the perfect read for anyone who loved Percy Jackson while growing up!
