Beside You| C.H The Mortal Instruments cross

You never truly appreciate what you have until its gone, is something Calum Hood learned the hard way, when his long time friend, and short time girlfriend, Cassandra dies suddenly; on top of that he's killed as well and thrown into an afterlife nobody predicted.

After all of this goes down, several intrudes from a different dimension appear out of thin air, leaving all members of G.O.D suspicious of their arrival.

Can the intruders find a way back to their own dimension before it's too late, and will Calum get the chance to apologize to Cassandra?
