Ancient Protector by Savannah Verte

Supervisory Special Agent Fedya Afanasi has a problem, and a secret. Unfortunately, he can’t solve his problem without revealing the secret, which could cost him his position, if not his job. Solving the case of the mystery plants and the explosion in the Back Bay Channel is only one piece of the picture. He’s hoping a survivor of the blast can offer some answers to what happened, and the solution to his problem, but she’s not talking.
Marietta Gomez has a problem and secrets of her own. She might be able to aid the investigation, but she’s on the run and not sharing information. When her plan to escape is thwarted, she finds herself back where it all began.
The stakes are high and climbing as the second mini-mystery in Making Waves reveals allies who aren’t and new adversaries to be investigated. Can the team find the answers they need, or are there too many questions yet to solve the puzzle? The best lead they have is beyond their reach and ready to weigh anchor for unknown waters. Time is running out.
