Sylvia Stryker Space Case/Sky Crimes and Misdemeanors Books

“ It's as if Star Trek married a cozy...very well done! Read and enjoy!” – Sharyn, Goodreads SET PHASERS TO COZY! Sylvia Stryker has no business on the next Moon Unit Cruise Line, unless you count aspirations and dreams. The career that once felt within her reach—Intergalactic Cruise Ship Security—disappeared the day her dad was arrested for collusion with space pirates. Since then she’s begrudgingly been running the ice mine for her aging mother, the two of them social pariahs amongst their fellow Plunians. Everything changes when the uniform lieutenant position on Moon Unit 5 opens up days before departure. Sylvia immediately puts her hacking skills to use, uploading bogus credentials onto the crew manifest. Now to just lay low, do her job, and impress the new boss. Her plan goes off without a hitch until a non-celestial body falls from the uniform inventory closet after departure. Reporting it means drawing attention, the very opposite of laying low. When the head of security shows up to investigate and throws her into the spaceship holding cell, her onboard status shifts from staff to prisoner. If Sylvia can’t expose the killer herself, she’ll be bunking with her dad at the local space prison. Fly Me to the Moon is the quirky first novel featuring uniform lieutenant Sylvia Stryker.

But when a space pirate bites the dust behind bars, and Neptune is framed as the culprit, Sylvia risks losing her Starman forever.

"a fun sci-fi setting with plucky enjoyable characters" - BookLife Prize Tomorrow is yesterday and next week may never come in this final adventure featuring space sleuth Sylvia Stryker! Sylvia Stryker is the Moon Unit Corporation’s employee of the month. Impressive, since her side gig solving intergalactic mysteries takes up most of her time. But she is put to a new test after her mentor, Neptune, flies through a wormhole to meet with a reclusive scientist about the faulty chip powering their lunar module. The contact has been hiding from accusations of murder on another planet. Even more startling is the identity of the scientist: a family member Sylvia never thought she’d see again. When Neptune’s space pod vanishes into a parallel timeline, Sylvia is quick to follow, but a face-to-face with her younger self threatens her reality. She is thrust into a time-bending journey where the unsolved murder becomes central to her mission. With a missing boss, a malfunctioning navigational system, and a family reunion hanging in the balance, Sylvia’s race against time just might save the world…or eradicate it from existence. Can Sylvia repair the circuits of time, or will she stay lost in space with a killer?
