Books about brothers discussion

By adventure I mean something like camping in the woods and so on, so don't get me wrong. These books seems like some for children, but still they are quite good.

From this section I would recommend:
The Last of the Chiefs
Ken Ward in the Jungle
The Young Lion Hunter
Der Ruf des Wolfs. cbt. (Volání vlka)
The Swiss Family Robinson
Adrift in the Pacific: Two Years Holiday

Not quite sure this fits, but I'm gonna put it here anyway.

The Sisters Brothers has two brothers as the main characters, and while goodreads give the main genre as historical fiction, there's quite a bit of adventure in it, as they're sort of cowboys and make a living out of killing people. It's quite good.

Not sure if this fits either but rise of the golden cobra by Henry Aubin is good (not about brothers but a strong bromance between the two main characters) it's set in ancient Egypt about a prince and a peasant, a little slow at the beginning but definitely a great read.

i don't know if this fits here but i think The Great Wide Sea is an adventure books. its about three brothers lost in the sea.

Definitely fits, second that.

Free Fall - one night read, very worth it! :) Just - why I feel everywhere the ending or a sequel is missing? But here it's just fine, I don't mind, it was just that good.

Oh, obviously I've forgotten this section existed, otherwise I'd put Rough Waters and Never Say Die in here instead of "Other books"...
