Madrigals.
Yes, in Book 7, Amy and Dan went to the Tomas stronghold in South Africa.
The theme is that Amy and Dan Cahill go on a hunt around the world to search for the 39 clues. Their competetors range from world leaders to artists and singers.

Based in book 10(Into the gauntlet) all of the branches meet to get the last clues which is Gideons serum but Isabelle Kabra appeared and try to kill all of them but Amy and Dan defeated her so when all branches (the Ekaterina,Lucian,Thomas,Janus) trusted them and they gave all their clues to Dan and Amy....so Amy and Dan won....
Amy and Dan are siblings. Amy loves Dan as a sibling and a brother.
Ekaterina, definitely. Because they are the smartest of the Cahill branches and can invent almost anything.( Example- they invented the atomic bomb! Isn't that just awesome?) Need I go on?This is what I found on a website.I think that the most likely choice is that Amy is a Madrigal and Dan is a Ekaterina. This is the way they strike me in; with Dan being smart and inventive; experimenting. Amy even called him a "natural Madame Curie," who happens to be an Ekaterina.In book six, Amy definitely proves she has Madrigal ability by tracking for trails; even though I'm pretty sure she's never been taught that.So I think Ekaterina is the best! Because Madrigal is not really a main branch.
In "The 39 Clues Book 5: The Black Circle," the main characters are Amy and Dan Cahill, along with their au pair Nellie Gomez. They travel to Russia to unravel clues left by their ancestors and face dangerous challenges from the mysterious organization, the Vespers.
