Gate Quest (Star Kingdom #5)

Roboticist extraordinaire Casmir Dabrowski has a new nemesis: astroshaman leader Kyla Moonrazor.

She’s stolen the ancient wormhole gate the king ordered Casmir to retrieve, and she’s entrenched in an underwater base on a forsaken moon. Moonrazor is more educated and more experienced than Casmir, and she has legions of killer robots and cyborg defenders on her side. Casmir has his friends and... a submarine named the Waddler.

As if his task wasn’t daunting enough, his old competitor, mercenary Captain Tenebris Rache, is on the same quest, and he’ll do anything to keep the Kingdom from getting that gate.

If Casmir can’t find a way to defeat them, the king will never let him return to his home, his family, and the career he loves.
