The Darkest Fire - Gena Showalter
A short introduction to this series and I enjoyed knowing how the demons escaped from hell, but most of all this is also a story about love through time.

We met Geryon and learned why he was the gates keeper in hell. His story is very sad and romantic because everything that he ever did was for a woman he fell in love. So Kadence was also part of his eternity and responsible to free him, but a great cost fell upon them and now the demons succeed in escaping, falling to the earth and bringing destruction.

But I actually liked how Kadence and Geryon discovered a way to finally be together, it’s so nice seeing him free after all those years and in love again.
