Looking to expand my sons' reading a bit - both keen readers and read well above their age but mostly fiction or "fact" type books.
I'd like to find some non-fiction that they would enjoy.
They are not interested in Sport really, eldest likes computers/maths/things to do with houses/building etc , camping/outdoors stuff.
youngest likes History (world wars etc), Japan, Cats, words and the both love Manga/Anime.
suggestions gratefully received - TIA
