Nebula Yorker ("Neb" to his friends) finds himself on the water planet of Marine in a race to recover a long lost Triopelian Star Chart he previously never knew existed.
Along the way Neb encounters new friends and a villainous brother and sister team bent on doing whatever they must to get their hands on the star chart first including mayhem and murder.
One cocky android, one imbibed professor, one universal(ly) renowned scientist and one ice breathing sassy Water Dragon makes Neb wonder whether the past 3 years travelling with Halley's Casino was just a peaceful lull?
Who will find the star chart first?
What are the implications if Neb doesn't?
And what does a Water Moon have to do with all of this?
