Well, they're actually cousins, first of all, and they're opponents. So, they're not really suitable for each other, but I would really like to see them together...... for real!
They already did!
In the "39 Clues" series by Rick Riordan, Amy Cahill and Ian Kabra do not get married. They maintain a close partnership and friendship as they continue their adventures together.
yes he is in love with Amy cahill.
Yes.
Ian Kabra. They break up.
Amy Cahill and Ian Kabra share a kiss in the book "In Too Deep" by Jude Watson. While stranded on a sinking ship, Ian promises to give Amy his locket, a family heirloom, if they make it out alive. Amy, to make the promise official, seals it with a kiss.
No they don't. Amy is with Evan and seems happy but I hope that they break up. A King's Ransom comes out in December so maybe they'll have some romance then.
Yes, but they don't actually meet eachover.
Grace and Fiske Cahill's car crash was orchestrated by Isabel Kabra, a member of the Lucian branch of the Cahill family. She was under orders from her mother, Cora Wizard, who is a part of the Ekaterina branch.
it is not directly stated but in a word yes
in book 3 it seems like he likes her but then he betrays her but in other books you can tell that he fell for her too
because Ian thinks Amy and Dan will be the ones that will get the final clue and wants to be with them. Also, Ian once described that he thinks Amy was shy and gentle. LOL
