Who writes Sunny Randall?

How the credits break down

Sunny Randall has 13 novels on file from 1999 to 2026. 7 of them carry a credit for a writer other than the creator. Because the byline changes, the credit for each book matters.

Mike Lupica has 4 book credits as the continuation author. The credits run from Robert B. Parker's Blood Feud (2018) to Robert B. Parker's Revenge Tour (2022). Since credits can change from book to book, the table below shows each one.

Alison Gaylin has 3 book credits as the continuation author. The credits run from Robert B. Parker's Bad Influence (2023) to Robert B. Parker's Booked (2026). While credits can change from book to book, the table below shows each one.

Roles matter here. A ghostwriter writes a book for someone else, while a continuation author carries a series on after its creator. Both get a credit on the book page. Therefore the byline tells you who wrote each novel. Credits come from public bibliographic and publisher records. We list them book by book, so you can check any claim. For the full reading order, open the series page.

Each writer's books follow on from the last, so the handover is easy to see. Even so, the full list is the best check, because a single credit can differ.
