The Fire Within Them is the second instalment on the Soulfire Saga, an epic fantasy proposal written by Matthew Ward, and published by Orbit Books. We return to the kingdom of Khalad, ruled by the Eternity King, and to our two sisters who are still struggling; but we become spectators of their growth into a world which Wards expands and improves.

Kat is still searching for a cure for the debilitating illness that eventually will end with her; but this time, she's not only a rogue fighting against the nobility, as she has become part of the Vallant. Despite that, we can still see how she tends to struggle with asking for help, but it's still a kind soul, as it is reflected in her interactions with the rest of the characters. Finding the truth behind her father's secrets is not an easy task, and in general, we can see that Kat has too much on his mind.
Remember Tanith, Kat's half-sister? Well, she's back in a spectacular way, and Ward decides to include her as a POV; she's not so focused on eliminating Kat, but her own path will be enlightening around the secrets that are under the surface of Khalad. I found myself enjoying so much each time Tanith took the spotlight, as they are some of the best chapters of the book.

With the descriptive and evocative prose that characterizes his writing, Ward continues expanding and developing the world, connecting some threads that were introduced in The Darkness Before Them; similarly to the first book, we could say that the pacing is relatively slow at the start, putting all the pieces on the board and preparing all for a great finale that in reality, leaves more questions that need to be answered in book 3.

The Soulfire Saga is the perfect election if you want a big and expansive epic fantasy series, with a second instalment that continues developing the characters and that doesn't have a single dull moment; I can't wait to see how Ward wraps all in the final instalment. A seriously underrated writer that more people should check.
