See it for yourself
the upper one is the author Kawakami Minoru's last work - 終わりのクロニクル, book 7 is the previous leader of the thickest light novel.
the lower is Kyoukai Senjou no Horizon
Moreover, the concept of his stories is very unique
I haven't read Kyoukai Senjou no Horizon yet but i have read 終わりのクロニクル
