Series I've Never Finished

Hello, my name is Abbey, and I have a problem. I read the first book in a series, and then I never finish the series. Even worse, I read the synopses of the rest of the series online because I'm curious to find out what happens, but I'm not curious to read the books myself!

If you have a fear of unfinished series, look away now.

1. Anne of Green Gables by L.M. Montgomery.
After reading Pride and Prejudice for the first time when I was fourteen, my mom suggested that I read Anne of Green Gables. I didn't want to read Anne of Green Gables, and I wasn't attuned to the language of classics yet, so I never read beyond Book 1.

2. The Hitchhiker's Guide to the Galaxy by Douglas Adams.
This is another book that I read when I was fourteen that I didn't enjoy much. I read it because I love the movie that stars Martin Freeman, but the book fell short of my expectations (I still rated it four-stars on Goodreads, though? I'm confused. Maybe it's time for a re-read).

3. Fever Crumb by Philip Reeve. Also, The Mortal Engines. 
I didn't continue with Fever Crumb because Philip Reeve killed my favorite character! After that, I lost interest in the story.
The two reasons I read The Mortal Engines is because 1) Jack Lewis Baillot raved about it on her blog a few years ago and 2) Peter Jackson is making it into a movie. I read the first book a few weeks ago and liked it, but I didn't like it enough to continue reading the series (especially after I read the synposes of the other books online).

4. Crater by Homer Hickam.
This is a great space book where people have settled on the moon. Even though I loved the first book, I've never gotten around to reading the rest of the series. I don't think I ever will.

5. Ender's Game by Orson Scott Card.
Again, a great sci-fi book. I've heard lots of great things about Ender's Shadow, but I never got around to putting it on hold at the library. I think by this time, I'd have to re-read Ender's Game before reading the next book.

6. Heist Society by Ally Carter.
This is a book that a friend recommended to me. It's about teens that go around stealing paintings for a reason that I've forgotten. It was okay, but I didn't feel compelled to finish the trilogy.

7. City of Ember by Jeanne Deprau.
I've read this book twice and enjoyed it both times, but have never been interested in continuing the story.

8. The Mysterious Benedict Society by Trenton Lee Stewart.
I loved this middle grade book when I first read it. If I had been younger when I read it, I definitely would have continued with the series. Because I was sixteen, I didn't read any of the other books. It's on the "Books to read to potential future children" list.

9. The Scarlet Pimpernel by Baroness Emmuska Orczy.
The Scarlet Pimpernel is a fabulous book and a fabulous movie. I have several of its sequels on my phone, but I don't like reading electronically. I'd love to read more Pimpernel books someday...

10. Eragon by Christopher Paolini.
One of my good friends read the Eragon series and loved it. I gave it a try and enjoyed the first book, but *shame face* I read the synopses of the other books online. They are so long, and Eragon was similar enough to The Lord of the Rings and Star Wars that I didn't want to put time and effort into the series if I could watch the same plot in movie form.

11. Twilight by Stephanie Meyer.
I've read this book twice, and, nope, I still don't have a desire to continue with the rest of the books.

12. The Inventor's Secret by Andrea Cremer.
I picked this one up in the YA section at the library. It had an interesting premise, but too much romance. If the second book had been out at the time, I might have continued. Now, too much time has passed, and I can't remember the plot, so I don't think I'll ever finish this series.

13. From Earth to Moon by Jules Verne.
This book ended in a KILLER cliffhanger (and poor Jules Verne's audience had to wait FIFTEEN years for the sequel!), but the writing is so sciencey that I don't know if I could handle reading the sequel.

14. The Looking Glass Wars by Frank Beddor.
This is the only book I've ever rated one star on Goodreads. Yeah, I won't be reading the rest of this trilogy. Ever. The characters were caricatures, the plot was cliche, and the writing was passive (just like this sentence).

15. Horatio Hornblower by C.S. Forester.
I have a love-hate relationship with nautical fiction. I love it because of the sea, I hate it because I have a hard time reading it, which is why I never continued on with Horatio Hornblower.

16. Illuminae by Jay Kristoff and Amie Kaufman.
Because this book has weird formatting and takes place in space, I thought that I'd love it. Unfortunately, I thought all of the characters were the same, and the swearing annoyed me because it was blacked out. Either commit to having swearing in your book, or don't include it at all. All that blacking it out does is draw more attention to it.

17. Heap House by Edward Carey.
This is one of the most unique books that I have ever read. I highly recommend it if you want something unlike anything you've ever read before. I'd like to continue this series, but I need to read the first book again before I can do that.

Here are three honorable mentions:

18. The Hunger Games by Suzanne Collins.
I read this book right as it gained popularity and then read the synopses of the other two books. In 2015, I re-read The Hunger Games and went on to read Catching Fire as well. I doubt I'll ever read Mockingjay, so this series will stay incomplete.

19. Inkheart by Cornelia Funke.
I love Inkheart. I think it's a fabulous book. I tried reading the sequel, but didn't like how dark it became. Also, Cornelia Funke killed my favorite character, so I kind of lost interest in the series after that.

20. Mistborn by Brandon Sanderson.
I loved the first book in this series! The second book dragged in the middle but became exciting at the end. I tried reading the third book, but I gave up. Maybe someday I'll finish Mistborn. I'd really like to because I really like Brandon Sanderson. He also killed my favorite character, though, and that's when I felt like the magic left the series (I'm sensing a trend here).

What I think we've learned here is that I lose interest in series when my favorite character dies, and that if I'm not invested in a series, I will take the lazy way out and read the synopsis online.

Have YOU read any of the series on my list? If you have, which ones should I continue?
