What do you think of my first book idea?

So I've been writing a series of books dealing with a charcter named Danny Jones. The first book in the series is called The Hourgl Plague, it sounds weird, i know. Well i think I'll skip the beginning because that's only relevent to the end of the series. But Danny somehow finds himself and his friends stuck under ground after excavating his schools rumored "underground tunnels" he then finds a place unlike any he's seen before. Its a large base that looks like a castle he curiously goes in and sees that people live there. King Poronac and his son tarool, along with their pet panther named dusk, so Poronac eventually recognizes over time that Danny has the same aura surrounding him as the ancient elemntal of fire, Blaze (long story) SO POronac lets him stay knowing that a child of an elemental could only bring trouble to his castle, Poronac shows Danny that it is not a normal castle, he brings him in a large room, it was like a zoo. Except there were no animals in the cages, they were mythical creatures, so POronac tells Danny that his family had been hunting mythical creatures on earth for centuries bringing them back into the castle and storing them. He also said that it was to erase the gruesome past that these monsters had on earth. So after staying awhile Danny finds out about Anxelo, the great lord of time. And also that Poronac is Anxelo's sworn enemy. So Danny his friends, and some of POronac's armies set out to Anxelo's base after learning that the evil lord of time had let loose a plague called the hourgl plauge, which causes everybody on earth's hourgl of life to speed up. They got to the base where they met Dynocaust a large black Monster that works for Anxelo, and also controls an army of Hydrakids, his minions. They get past him, but also find Anxelo's ins, Jester and Darc They fight them, kill Darc and jester flees, Danny's friend Carson picks up dead Darc's magician hat, puts it on, and is gifted with the the power of the black seige which is almost like the force but you can actually see it. So they find Anxelo, and see the hourgl that holds he l;ife of the plague, but as you know Anxelo's not going to really give up world domination without a fight. POronac's army men tell Danny and his friends to sneak around and destroy the hourglass while they hold Anxelo off. Well, suprise suprise the army men die. And Anxelo is after Danny now. Anxelo shot a blast of razor sharp sand at Danny, (sand that could disentigrate somehow) yah, his powers are that cool. So Carson pulls Danny out of the way and the sand hits the hourglass, shattering it, and ening the plague. Yah shoot some disentigrating sand in the direction of your plague source why dontcha Anxelo (dumbass). So Anxelo's pissed and before he completely kills them, Dusk the panther knocks everybody down onto a metal plate and pulls them back to Poonacs castle, so yah, hes pretty fast. So yah and thats about it. tell me what you think
