Your Device 4.0 Black Dragon Wedding by Keith Thomas LaSpaluto

Your Device 4.0 is just like your last one, human. It has a newly tuned crystal and retains all the portal reconnection properties. Use it as normal, and connect to your host often.

You wonder what happened to version 3.0? What is Parks' fate? The next exciting adventure is supposed to be a wedding in autumn. Then that demon showed up south of Einsle, causing havoc. You plunged into battle to defeat it, following the guidance of your companions only a little too precisely. Now you are unable to connect back to Aarth and your host. Is Parks even still there, or has your host, your friend, been obliterated from existence? You get nothing through Your Device. What will you do now?

Sooner or later, you might just have to face the possibility that your time on Aarth is over. Will you be able to reconnect again? Will Parks be on the other end of Your Device? There's only one way to find out.
