Hero Rising, The Four Book Secret Guardians Boxed Set, Secret Guardians Book #1 by H.T. Night is a grand adventure. I gave it four stars.
The Tandra world are humans. Josiah goes on a crusade to help them escape the evil that surrounds them. He becomes a protector and superhero. He is also a vampire and a werewolf but is not immortal.
He heads for New York along with Tommy, the werewolf. Tommy was engaged to his sister before the accident killed her and her parents. After that, they bonded and were like brothers. Tommy now is a coach for MMA fighters.
Josiah flew in his eagle form to San Bernardino where he came across a building on fire with people trapped. "But fire. Yeah, I was cautious about my own hide like that. But there was no way I could turn my back on the....If I didn't help, if I walked away from people who could have been saved; it would haunt me for the rest of my days."
I bought it and read it in one sitting. I look forward to reading Hero Unbound (Secret Guardians Book 2).
