My Sister's Keeper discussion

Is Campbell a recurring character in any of Picoult's novels? I heard he was. If so, what are the titles?

Not that I'm aware of and I've read all of her books.

According to Wikipedia these are the only recurring characters in Jodi Picoult's novels:

Jordan McAfee, his son Thomas, and his wife Selena are featured in The Pact, Salem Falls and Nineteen Minutes.

Patrick Ducharme, a detective, is featured in Perfect Match as well as Nineteen Minutes. She has stated that she brought Patrick's character back for a second novel because she has a crush on him.

Ian Fletcher of Keeping Faith makes a brief appearance in Change of Heart, published in 2008.

Frankie Martine, first featured in Salem Falls, returns in Second Glance, and Perfect Match.

Nina Frost, a main character in Perfect Match, is mentioned in Nineteen Minutes.

Peter Houghton, a main character in Nineteen Minutes, is mentioned briefly in House Rules.

And now Jordan & Selena are in her newest book Mad Honey!

Jordan mcAfee is also in her new book mad honey.
