Witches, Wings, and Fluttering Things

Iris is a witch with a secret. It's not that they're a lesbian (that cat's been out of the bag since they were seven), it's not even that they're a witch (it's become so mainstream now that their school even has clubs). No, Iris's secret, like all the best things, is a magical girl. The faery they accidentally summoned at six then kept meeting up with in secret.

Until Agnes suddenly decided that she was bored with them a few years ago and stopped visiting.

When Iris's secret comes out and they realize that their connection to Agnes might be their ticket to finally being noticed in the human realm, they summon her at a party. But when an attempt to trick Agnes into staying longer goes wrong she ends up trapped in their realm, gradually becoming weaker as her connection to Faerie fades. If only the only way to set things right wasn't offering the girl who now hates Iris back safe haven, as their roommate.
