The Sparklers

Nova and Adrian Burgess are sent to stay with their grandparents who they barely know in the middle of nowhere for two weeks, and they are less than thrilled, especially since it's only been a year since their mother died, and their grandparents didn't even show up for the funeral. Adrian is very excited to go and explore the forest, but grandpa says that going into the woods is forbidden. Nova is perfectly fine with just sitting by the pool and relaxing. Adrian isn't very good at following rules though, and Nova makes sure to keep and extra eye on her younger brother. But Adrian ends up stealing a mysterious note from grandpa's office, which leads him and Nova to a secret island in the woods called Penethon Isle, where they learn about the Sparklers. The Sparklers are being with auras that dictate what magical ability you have and what you can do with it. But the Sparklers were forbidden to make any contact with regular humans by the government, so the Council of Sparklers hid Penethon Isle, and every Sparkler must guard their secret very well. Nova and Adrian find out that they are linked to a mysterious legend about the silver and gold auras, which gives them the power of light and darkness. Because of this, a mysterious Sparkler known as Japeth, wants to get them and destroy the humans because of their hatred for the Sparklers. Will Nova and Adrian be able to stop him?
