Daemons. The Riddle of the Storm, #1

Seeking solace in a remote mountain cabin in northern Maine, haunted by the recent loss of a comrade during an operation in Afghanistan, Special Operations Operative, Hal Bennet questions his sanity when awakened in the middle of the night by what appeared to be a medieval knight. No sooner has the man calling himself Crown Prince Henry Lackland introduced himself to a confused Hal, than the knight is whisked away once again during a strange and terrible storm.
The sudden and unearthly disappearance leaves the Special Forces Operative questioning his own sanity. But Henry left proof of their encounter-his chainmail and sword. Haunted for a year by the strange encounter, Hal is driven to return to the same mountain cabin, hoping to find answers to the questions that constantly circle in his mind. How did this happen? Why did it happen to him? And where did Henry go? Uncertain of what lies ahead, he ventures forth into the same terrible storm and similarly vanishes.
Upon waking on the isle of Glenlock, Hal finds himself thrust into a world of kingdoms populated by civilizations from Earth's past. A world where malevolent forces are lurking as bands of strange-looking men, deformed daemons bent on destruction and abduction, threaten the land. Can Hal overcome his past demons to rise to the fight ahead, or is Glenlock destined to fall into darkness?
