The Heart of the Radiant - Daniel Kogler - Bog

A band of heroes must embark on a perilous journey to prevent an ancient king from bringing about the return of the most powerful being in the world.
Aspiring cadet Jax Ruthoree finds himself traveling with the last surviving members of the Light Guard after his home city was decimated by the Undead King Dezeroth and his hordes. Outnumbered and on the run, the group has but one goal: to keep the Heart of the Radiant out of Dezeroth's hands... at any cost.
Now, the group must journey through the hostile environments of Doxla in a desperate effort to carry the Heart to safety, all while Dezeroth’s forces hunt them down relentlessly. Little do any of them realize the true stakes at hand, or what heavy price of success they may have to pay in the end.
