When one of Magnus's spell goes haywire, Jace, Simon, Alec, and Magnus, get sent into a different world...The Iron Realm. The Iron Realm is ruled by queen Meghan and her husband Ash. This world isn't like anything these fellow ShadowHunter's are used to. No, instead of demons, they are met with some nasty little gremlins, a trickery summer fey that loves to pull tricks, and a... talking cat? Will Magnus be able to get everyone home safety, or will they be stuck in the land of the fey, forever?
