The Wastes (The Starship In The Stone, Book Four)

Thomas and his crew face their most dangerous quest yet. Morgana's forces are searching for something ancient and powerful, and they need to get there first.

Some boundaries were never meant to be crossed.

The Wastes—a cosmic dead zone where sensors can’t be trusted and those who enter rarely return. As Excalibur ventures into this treacherous domain, Thomas must navigate not only the physical dangers but also mysteries that have remained hidden since long before Arthur's time. 

With Turquine in relentless pursuit and tensions mounting among allies pushed to their limits, Thomas and his battle-worn crew must rely on every skill, every resource, and every bond they've forged to survive. 

What they discover could change everything.
