Reaper's Lottery

"Their first-ever serial killer is stalking the crew of the high-tech starship the Reaper's Harvest III, but despite it all, the anthropomorphized geroo Tori has no access to any forensic science. If she wants to save her best friend's life, she needs to think of a new way to solve the crimes ... and fast!" ― paraphrased from this book's product page on Amazon.com website as of 2019-07-08.
