Hello guus i want to recomend a book to you, and if you look at the cover it's not about angels and stuff. It's called Generation Icaris: first flight, by JLpawly. It's really an amazing book, and it's worth while to read it! You'd be doing me a favour too, because the author won't post the last book because she wants about 7k of reads on the first one. You don't have to if you don't want to. :)
