This topic was a tricky one. Lots of the books I love have sequels, and many of my favourite standalones have neat, tied-up endings and don't provide any material for a potential sequel. That's why I could only manage a Top Eight!
Top Eight Books I Wish Could Have Had Sequels
1. Dramarama, by E. Lockhart - I would love to know what Sadye did next! There are hints about the path she might take but I'd love to read about it in full.
2. The Disreputable History of Frankie Landau-Banks, also by E. Lockhart - It's a brilliant standalone but I think it's impossible to love it without wanting, even just a little bit, to find out what Frankie does next. Even if only at university. Or in senior year of high school!
3. Journey to the River Sea, by Eva Ibbotson - Need more Miss Minton. That is all.
4. Janes in Love, by Cecil Castellucci and Jim Rugg - This is itself a sequel to The Plain Janes, and there was supposed to be a third in the series, Janes Go Summer, but it was cancelled when the imprint was closed. Oh, comics industry.
5. Everything Beautiful, by Simmone Howell - I just want to spend more time with all the characters! I wonder how things work out between Riley and Dylan, and Riley and her stepmother.
6. Notes from the Teenage Underground, also by Simmone Howell - What does Gem do next? Don't get me wrong, both these books are wonderful as they are, great standalones! I am just really curious.
7. Matilda, by Roald Dahl - wouldn't you just love to know what she's like when she's a bit older?
8. Diary of a Grace, by Sarra Manning - I know why this has no sequel, but the little bit of me that is still fifteen desperately wants to know whether she stays with Toph or gets back with Jack!
Do you share any of my choices? Isn't it completely annoying when sequels are cancelled? I know that happens fairly regularly with paranormal romance/urban fantasy series that don't do as well as the publisher and author hoped. Has it ever happened to a series you loved?
