This manga 4-book series starts off in a day school that becomes a night school at 6pm for other worldly teens (weirns, werewolves, vampires oh my). I only have two of the four books but the books follow Alex, a homeschooled weirn who enrolls in the nightschool when her sister, who worked at the nightschool disappears.
If you like manga, but hate that the Japanese manga make you read backwards, this one is for you. If you cannot afford the manga series that seem to come out weekly for years, this one ends at 4.If you love the character styling of manga where everyone looks androgynous and European, this is for you.
I liked the story enough. It fit the category of manga, cliff hangers and all. I think it taps into the fascination with non-human teen characters. Is it a keeper? No, but it's a reader. Find a public library or a well-stocked English classroom and just borrow it.
