“The plot twists will give you whiplash.” –Washington Post Read the #1 New York Times bestselling thriller Invisible, then continue the series with Unsolved. 
FBI researcher Emmy Dockery is obsessed with finding the link between hundreds of unsolved cases. All she has are the newspaper clippings that wallpaper her bedroom—no motives, no murder weapons, no suspects. That is, until she finds a piece of evidence she can’t afford to ignore. Could one person be invisibly connected to these unthinkable crimes?

“Top-drawer crime fiction ... tough on the hero, but the hero is tough.” –Kirkus Reviews
