The Michael Bennett series by James Patterson has 17 books and is best read in publication order, starting with Step on a Crack (2007). The next book, Delusional, is due 17 August 2026.
Start here: Step on a Crack (2007) — then read straight through in publication order.

The order the books were released — the default way to read the series.
Detective Michael Bennett works major cases for the NYPD while raising ten adopted children alone in a cramped Manhattan apartment, with his grandfather Seamus (a wisecracking retired priest) and, later, nanny-turned-partner Mary Catherine holding the household together. That domestic chaos is the series' secret weapon: Patterson pairs it against some of his most theatrical New York set-pieces — hostage sieges at St. Patrick's Cathedral, a serial killer targeting the city's elite, international manhunts that pull Bennett out of the five boroughs entirely.
James Patterson launched the series in 2007 with Michael Ledwidge, who co-wrote the first nine books before James O. Born took over the collaboration from Haunted (2017) onward, steering the later entries toward tighter, more procedural plotting while keeping Bennett's family front and center. Two shorter BookShots entries, Chase and Manhunt, slot between the numbered novels as quick standalone side-cases.
Running parallel to Alex Cross as one of Patterson's two flagship NYPD-adjacent series, Michael Bennett has become one of his longest-running and best-selling continuing characters, with new entries still arriving on an almost-annual schedule.
Read in publication order starting with Step on a Crack (2007) — it introduces Bennett, his ten kids, Seamus and the found-family dynamic that every later book leans on. Story chronology matches publication order throughout, and Bennett's family situation (his wife Maeve's death, his relationship with Mary Catherine, the kids growing up) develops continuously across the series.
The two BookShots novellas, Chase (after book 9) and Manhunt (after book 10), are quick optional side-cases rather than essential reading — skip them without losing any of the main throughline. The 2017 handover from co-author Michael Ledwidge to James O. Born is seamless in tone, so there's no need to treat the two halves of the series differently.
17 main novels, from Step on a Crack (2007) to Paranoia (2025), plus two shorter BookShots novellas (Chase and Manhunt). Book 18, Delusional, is scheduled for August 2026.
Publication order, beginning with Step on a Crack. Bennett's family situation and personal relationships carry forward continuously from book to book.
Michael Ledwidge co-wrote the first nine novels (2007-2016); James O. Born has co-written every book since Haunted (2017).
They're official Michael Bennett side-stories in Patterson's shorter BookShots format, but optional -- the numbered novels tell a complete story without them.
No -- they're separate NYPD/DC-set series by Patterson with no shared characters, though fans of one series' short-chapter, family-anchored formula often enjoy the other.
