Happily Ever After: Companion to the Selection Series is an illustrated hardcover which includes all already published novellas and new ones. It was published October 13, 2015.
Meet Prince Maxon before he fell in love with America and a girl named Amberly before she became queen. See the Selection through the eyes of a guard who watched his first love drift away and a girl who fell for a boy who wasn’t the prince. This gorgeous collection features four novellas from the captivating world of Kiera Cass’s #1 New York Times bestselling Selection series—two of which appear here in print for the first time — as well as exclusive, never-before-seen bonus content.
According to Kiera Cass: "This was going to be the cover art for Happily Ever After, and I totally love it. BUT it was thought by some that it might be less recognizable without America on the cover, so it was changed to her face. Just a little note on how covers work. This is also why things get changed halfway through a series. Trying to make it work."
The book is only about the first generation of The Selection series. Thus it doesn't include any information about Eadlyn's Selection in The Heir and The Crown.
