   Summary

   Ryland quickly pulls up the helioscope’s feed again and they have a much clearer view of the ship this time. The front of it is slightly crumpled and the entire thing looks like it’s seen better days.

   But Simon’s eyes are drawn to the familiar logo painted on its side. He tightens his grip on the pilot seat. “I know that ship. We need to get closer.”

   “Wait, what—?” Ryland asks but Simon cuts him off.

   “My sister might be on that ship. She could be in danger, we need to find her.”

   OR

   An AU where Anya and Simon are siblings! After two decades of the siblings being separated, Grace, Rocky and Simon find the Tulpar floating in space and decide to investigate.
