Is this a good idea for a possible novel?

Brad and Jasmine live in Chicago, Illinois and attend Benjamin Fullmer Middle School. When they are attacked at their school assembly for bullying by the Egyptian god Apis, they are taken by their history teacher Mr. Salvadore to the Lair of the Gods which is on the tip of Willis Tower. The Lair of the Gods is where the Egyptian gods Isis, Osiris, Horus, Set and Nephthys live, along with other minor gods and their servants. While there, it is revealed that Mr. Salvadore is actually the Egyptian god Heka who was sent by Isis to watch over them. Isis reveals that Jasmine is her descendant, and that Brad is the descendant of an unknown god. Horus explains to them that a very powerful dark force is awakening and is trying to kill his descendant Kevin. Brad, Jasmine and Heka go on a quest to save Kevin and they encounter many Egyptian gods that are minions for the the dark force that is emerging. This dark force is revealed to be the god Apep, and that the reason Brad was chosen is because Brad is the descendant of Ra, the sun god and the enemy of Apep. When they return to the Lair of the Gods, it is revealed that the Prophecy is being unraveled and that Brad must be the one to defeat Apep with the help of the five descendants of the main gods.
