"This is a five-star series. Loved it!! Can't wait for the next one, please!!" FBI Agents Donovan and Eleri left their last case with a sense of unease. Unable to close the investigation, they've been thrown into their next assignment far too fast. A string of strange arson-based murders are just part of the trouble. Not only is former agent Wade de Gottardi on their team for this one, so are two other NightShade agents: Dana Brantley and Christina Pines. The problem is, Eleri is no longer the senior agent, Dana is. Maybe their boss no longer trusts them, or maybe it's simply because four people have already died. Either way, Donovan and Eleri are no longer in control of the case as they hunt a serial killer who's getting bolder with each success. While Eleri and Donovan are just getting their special skills in hand, Dana and Christina are more at ease with theirs. While Dana's talents prove useful, Christina's are frightening . . . and suspicious. As old cases rear their ugly heads, Eleri and Donovan get drawn into the mysteries of their fellow NightShade agents. Will their new team implode from distrust before they crack the case? Their unique talents may not be enough to save them from a seemingly unstoppable killer. Echo & Ember is the fourth book in the NightShade Forensic FBI Files series by USA Today bestselling author A.J. Scudiere. This book can be read as a standalone, but readers who love paranormal investigations and FBI thrillers will want to read the entire series!
