Books that Launch a Super Long Series
I love a good long book series. If you've ever read one of my reviews, you've probably seen me say that I want another book about another character, or an expansion of something that was briefly mentioned, or just...MORE. If I love a book, I will never complain about there being another story added to it.
That being said, there can be some cons to reading a super long series. Sometimes the storyline is drug out to fit a certain number of books when it could have fit into less. Sometimes the publisher doesn't give the entire series the green light if sales haven't been very good (there are a lot of readers who won't read until a series is finished, which obviously takes longer for a longer series). Sometimes an author passes away before they can finish writing all of the books they had planned, or just loses inspiration a few books in.
If you're like me and LOVE reading long series, I have some great series starters listed here. Get your TBR ready for the next summer challenge, or just continue building your stack so high that you'll never get through them all (not speaking from personal experience or anything).

Crystal Dragon by Katie Cherry
7 book series

I may not have been satisfied with farm life on Earth, but I certainly didn’t want all this.
Kidnapped and taken to a magical realm called Zilferia. Assigned a partner and a coach and thrown to the mercies of the realm’s creatures in a desperate bid to grow into magical powers gifted to us from the realm itself. Avoid getting caught by the realm’s violent, self-proclaimed ‘Dragon Hunters.’
Sure, my partner Nathan quickly becomes a good friend to me, and sure, I love the magic and the dragons here, but make no mistake- I’d rather go home.
I’m not their lost princess. I’m not some half-dragon shifter freak.
I’m certainly not destined to save the seven realms from destruction.
