The earliest SVH books (except for Double Love) had considerably less pages than others. Some of these early books were bulked up with extra content added to the back, such as lengthy synopses of existing books in the series, previews of upcoming books from SVH and the Caitlin series, and … drumroll … the character bios shown below. Click each picture to enlarge it. (Thanks Liesel for asking for these!)
This lengthy bio of Bill Chase appeared in the first edition of book 5.
More about Jessica's infatuation with Bill and Bill's dead girlfriend Julianne
More about Bill's parents than we've ever heard in the books, and the start of Lila's biography.
A rather shattering revelation about Lila's father and some info about Lila's "true love"
The last part of Lila's bio
The back of book 6 featured a Roger Collins biography. Notice it says that Elizabeth and Mr. Collins are "close friends."
...in which we learn about Mr. Collins' ex-wife May and how she kidnapped Teddy after losing the custody battle.
Some foreshadowing of the Mr. Collins-Ms. Dalton bit in Perfect Summer and a strange bit about Jessica's crush on Mr. Collins and her eagerness to babysit ... I didn't know Jessica cared.
There you have it! Have you ever seen any more of these biographies in any SV books? These are the only three I am aware of.
