The Atlee Pine series by David Baldacci has 4 books and is best read in publication order, starting with Long Road to Mercy (2018).
Start here: Long Road to Mercy (2018) — then read straight through in publication order.

The order the books were released — the default way to read the series.
Atlee Pine is an FBI special agent working the Bureau's most remote territory — the rural Southwest — whose entire career has been shaped by one unsolved trauma: as a child, she watched her twin sister Mercy get abducted, and Mercy was never found. David Baldacci opens the series with Pine chasing present-day cases (a mine disappearance, a serial-killer investigation) while the cold case of Mercy's kidnapping runs underneath every book, finally taking center stage as Pine goes rogue to find the truth herself. It's a more personal, psychologically driven series than many of Baldacci's other thrillers, built around one investigator's decades-long search for closure as much as any individual case.
The series is short but tightly serialized — only four books, with the abduction mystery resolving by the final one — and includes a direct crossover with Baldacci's John Puller series in Daylight (2020), where Pine and Puller's investigations intersect. It's a good fit for readers who want a female-led FBI thriller with a strong emotional throughline rather than a purely case-of-the-week structure.
Publication order, starting with Long Road to Mercy (2018). Unlike many long-running thriller series, Atlee Pine tells one serialized story across all four books — the search for her abducted twin sister Mercy — so it should be read in strict order, ending with Mercy (2021), which resolves the central mystery.
Daylight (2020), the third book, is a direct crossover with Baldacci's John Puller series; reading the first two Puller novels isn't required, but knowing who Puller is going in helps that book land.
There are 4 Atlee Pine novels: Long Road to Mercy (2018), A Minute to Midnight (2019), Daylight (2020), and Mercy (2021).
Publication order, in strict sequence. The series tells one serialized story — the search for Pine's abducted twin sister — that resolves in the fourth book, Mercy.
Both — it's a direct crossover featuring both protagonists, counted as book 3 in the Atlee Pine series and book 5 in the John Puller series.
Effectively yes — Mercy (2021) resolves the central mystery of Pine's sister's abduction that drove the whole series, and no further Atlee Pine novel has been announced since.
No. Both series can be started independently; they only intersect directly in Daylight, the third Pine book / fifth Puller book.
