All her life Jenna has strived to reach the Tagrale, the gateway to the stars, but if she does she'll be executed for a crime someone else committed.

For hundreds of generations scientists have tried to reactivate the Tagrale and escape the Sironus system.  All have failed.  Since childhood Jenna dreamed of being the one to unlock the puzzle, but how can she if she can't even go near it without forfeiting her life?

With her plans in ruins and a ship that has fallen apart around her, her dreams seem to be long dead.  Then she receives an offer of work which is tantalisingly vague but will set her on the path to her dreams once more… and bring more danger than she could possibly imagine.

Will Jenna reach the Tagrale?  Will she be able to solve its puzzles?  Or will the dangers overwhelm her?
