Lincoln Child introduced Jeremy Logan in Deep Storm, published in 2006 at 432 pages -- the longest book in the series -- setting the template for an "enigmalogist" who applies rigorous scientific method to a case, here a mysterious ailment sweeping an Arctic research base, that looks supernatural on the surface.
Alternative text for cover: Cover of Deep StormTerminal Freeze followed in 2008, the second entry at 429 pages, nearly matching Deep Storm's length as Jeremy Logan's investigative method -- assume a rational explanation exists, then find it -- is put to the test in another isolated, ice-bound setting.
Alternative text for cover: Cover of Terminal FreezeThe Third Gate arrived in 2012, four years after Terminal Freeze, as the third book at 416 pages, continuing Lincoln Child's slow-burn structure of a Yale-affiliated investigator working a case that keeps readers guessing whether the supernatural is real.

Alternative text for cover: Cover of ChrysalisDr. Jeremy Logan is an "enigmalogist" -- a Yale-affiliated investigator of unexplained phenomena who applies rigorous scientific method to cases that look supernatural on the surface: a mysterious ailment sweeping an Arctic research base, ghost sightings tearing apart a Massachusetts mansion, unexplained deaths circling a remote lighthouse. Lincoln Child writes the series alone (without co-author Douglas Preston), using Logan's investigative method -- assume a rational explanation exists, then find it -- to structure each book as a slow-burn mystery that keeps readers guessing whether the supernatural threat is real or engineered.
The series runs from Deep Storm (2006) through Chrysalis (2022), spanning underwater research stations, isolated wilderness, gothic mansions and other classically atmospheric settings that let Child indulge his taste for claustrophobic, slow-building dread.
Six: Deep Storm (2006), Terminal Freeze (2008), The Third Gate (2012), The Forgotten Room (2015), Full Wolf Moon (2017) and Chrysalis (2022).
Each book is a self-contained case, so any order works, though publication order is the most natural default.
A Yale-affiliated 'enigmalogist' who investigates apparently supernatural phenomena using rigorous scientific method.
No -- this is Child's solo series, written without Preston, and has no crossover with Pendergast, Gideon Crew or Nora Kelly.
No further title had been announced since Chrysalis (2022) as of this writing.
