Dr. Aris Thorne and his assistant, Mia Rodriguez, are no strangers to strange cases. But when a brilliant but prickly rodent geneticist is found dead in his lab, they're thrust into a world of high-stakes science and ethical controversy. The police are quick to label it a lab accident, but Mia's instincts and the disappearance of the doctor's prized albino mouse, Snowflake, tell them otherwise.

As they delve into the cold, clinical world of genetic research, they discover a cast of brilliant minds with dark motives. Suspects include a rival geneticist who stood to gain a massive grant, a recently fired lab assistant with a grudge, and a pharmaceutical CEO with a secret disagreement with the deceased. With Aris's uncanny ability to read animal behavior and Mia's street smarts, they must interpret the silent cues of the other lab mice to uncover a web of lies and expose the killer.

They're in a race against time to find Snowflake and get justice for the doctor before a groundbreaking scientific discovery falls into the wrong hands.
