She wants to free her mentor from jail. A frame-up keeps him trapped in the system. Can she expose corruption and get him out? Uniform Lieutenant Sylvia Stryker is about to take off on her fourth Moon Unit Cruise. Her family is gone, her planet was blown up, and her mentor, Neptune, is behind bars indefinitely. But when a space pirate is murdered inside the space prison and Neptune is assumed guilty, Sylvia might lose him for more than the duration of his sentence. Forget the stability of her job for Moon Unit Corporation. Losing one more person might leave Sylvia isolated forever. Faced with possibly-corrupt galactic government, a team of questionable freelancers, and the limits of her physical capabilities, she goes all-in to get him out. If she fails, she'll lose the only connection that gives her hope for the future. Can Sylvia design a successful mission on her own to save the person who taught her everything? Spiders from Mars is the fourth quirky adventure in the Sylvia Stryker Space Case mystery series. If you like resourceful characters, unique settings, and outer space fun or read favorites like Charlaine Harris or Dakota Cassidy, then you'll love Diane Vallere's entertaining interstellar series.
