Sylvia Stryker Space Mysteries

Brilliant minds. Bold questions. Deadly consequences.

Computer hacker and dry ice miner Sylvia Stryker solves problems for a living—so when murder crashes into her orbit, she does what comes naturally: she follows the evidence. Armed with logic, curiosity, and a refusal to look the other way, Sylvia uncovers secrets others overlook, even when the truth is dangerous.

The Sylvia Stryker Space Mysteries combine classic cozy whodunits with a smart STEM-forward twist. Set against a backdrop of space, innovation, and big ideas, these mysteries deliver clever puzzles, dry humor, and a heroine who proves that brains—and bravery—are a powerful combination.

Each book is a complete, fair-play mystery and can be read as a standalone.

In this series, you’ll find:

  • A sharp, STEM-savvy amateur sleuth
  • Clever, fair-play mysteries
  • Light science-forward settings with cozy appeal
  • Intelligent humor and thoughtful problem-solving
  • A confident heroine who trusts her mind

Step into Sylvia Stryker’s world—where curiosity is essential, logic is lethal, and murder is anything but theoretical.
