Invisible Books in Order

The Invisible books center on Emmy Dockery, an FBI research analyst whose talent for spotting patterns borders on obsession. When she looks at case files full of accidental deaths and unexplained house fires, she sees a single killer hiding behind tragedies everyone else has written off.

In Invisible, Emmy is on leave from the Bureau, grieving her sister’s death in a fire that investigators called an accident. She lives in a bedroom papered with news clippings, chasing a theory no one believes. The only person she can still turn to is her ex-fiancé, former agent Harrison Bookman, nicknamed Books, who reluctantly helps her reopen old files.

Once Books and a small team begin to dig, they uncover hundreds of suspicious incidents scattered across the country. No obvious motive, no forensic trail, and no clear link between victims—all of it pointing toward a sadistic killer who has learned how to make murder look routine. As Emmy pushes the investigation forward, she risks both her career and her sanity.

Unsolved picks up with Emmy back inside the FBI, her skills now grudgingly acknowledged. She starts seeing a new pattern in deaths that look natural or accidental, just as the Bureau is rocked by leaks and internal suspicion. While Emmy quietly tracks what might be a second invisible killer, Books is asked to investigate whether she herself is the source of the leaks.

The tension in this series comes as much from institutional resistance as from the crimes themselves. Emmy is brilliant, wounded, and sometimes reckless, constantly battling bosses who think she is seeing things that are not there. Readers who enjoy profiling, data-driven investigations, and cat-and-mouse games with a nearly undetectable villain will find plenty to keep them turning pages.

These are dark, propulsive thrillers that still make room for the complicated pull between Emmy and Books.
