It isn't out yet but it comes out later this month, its the first book of a series of 9 by an up and comming author named Ryan Tomasella. Drylor The First Artifact is the first book in the series and it follows a man named Von as he struggles to regain his memory and stop his brother from destroying everything.
The back of the book:
When a man wakes up inside a cage that is being carried through
an underground city, he has no idea where he is or what has
happened to him. As Von, a victim of amnesia, is taken to a jail
cell to await his fate amongst elves, humans, dwarfs, gnomes, and
halflings, he is told he is a member of the Royal Guard of Genisus.
It is not long before he is transported to the palace where he
meets an impatient king who eventually returns him to his jail
cell while deciding his destiny.
As Von’s memory slowly returns, he discovers that he is the only
one who can protect Drylor—a world that abandoned him—
from its greatest evil, his own brother. Through his journey to the
truth, Von meets an unlikely group of friends who are willing
to sacrifice everything to help him stop his brother Scarlet
from annihilating the only world they have ever known.
As Von’s past becomes clear and reveals his future, he soon
realizes the only way he can end his brother’s heartless
massacres is to find him and kill him.
For how long the information about this book has been out, it's developed quite a following on facebook already. It's something I would definitely recommend checking out.
