On Tuesday, Kendall and Kylie Jenner sat down with the morning talk show Good Morning America to dish on their big sister Kim Kardashian’s wedding.

Kim and Kanye West’s wedding was one of the most talked about weddings of the year, and the Keeping up with the Kardashians stars revealed all the intimate details, saying that the wedding was full of love and they wore beautiful gowns picked out by the bride and groom.

“The whole wedding was just filled with so much love,” Kylie said. “It was just really amazing to watch that and be there.”

“Honestly, everything was amazing.… And to see two people so happy. I think that that was probably my favorite part,” Kendall added.

“Two cities… Two girls… A shared destiny…” the synopsis from amazon.com read. “In a world of the far future, the great city of Indra has two faces: a beautiful paradise floating high in the sky, and a nightmare world of poverty carved into tunnels beneath the surface of the earth. Kendall and Kylie Jenner, the youngest sisters in the Kardashian dynasty, have written a gripping tale of air, fire, and a bond of blood.”
