I LOVED all of these books:
Percy Jackson/Heroes of Olympus (stan nico)
Goosebumps series
Hunger Games
The Call of the Wild
Among the Hidden - Probably my favorite book series to this day. It’s about a boy who was the 3rd born child in his family. Children like him are called ‘shadow children’ In this world, you can only have 2 children, or the 3rd will be killed by the Population Police and yada yada. It’s about how he has to live among his family and (more stuff I can’t say because it’s a spoiler) but ITS SO FREAKING GOOD
I do have to warn you though, there’s a lot of violence in this series, so if you aren’t into that then I wouldn’t recommend it.
