James Carstairs and Will Herondale are never apart. So it makes sense that they would get lost in 130 years in the future- right? One day, they leave to go to an Enclave meeting in New York. Magnus and Henry make them a portal and they arrive safely- but in the wrong time. What was suppose to be an ordinary trip turns into an extraordinary adventure. Enter Clary, Jace, Izzy, Alec and Magnus. Fresh out of a war and they already have trouble brewing. Not to mention Zachariah- the mysterious young man who used to be a silent brother and has ties with the warlock, Tessa Gray. Join Jem and Will as they face demons, time travelers, automatons, and immortal cats. This is not your ordinary Infernal Devices crossover. After City of Heavenly Fire and Clockwork Prince. **All chapters at least 1,100 words**
