A few years ago, I spent most of my savings on The Lunar Chronicles by Marissa Meyer (Cinder, Scarlet, Cress, Winter, and Stars Above; I didn’t get Fairest), read them all, and loved them…though I didn’t reread them and sold them some time later.
And what was the first series you spent most of your savings on?
The Shannara Series is the first I actually bought however I had read LOR before that
Edward Eager’s Tales of Magic (7 books)
I’ve loved them ever since I got Half Magic from the public library one summer
Probably cherub or the edge chronicles (fantastic fantasy series with lovely omnibus editions for the 2nd/3rd trilogies) curse of the gloamgozer etc
The Sword of Truth, back when Confessor was the last book.
The Wellworld series (fantasy) by Jack L. Chalker back in the 1980s. I still have them but little desire to revisit them as so much else that needs reading.
The only other series that has taken me is the Millennium Trilogy by Stieg Larsson, which had me losing sleep to read. Had he lived, I would have followed the series as long as it lasted.
Maximum Ride by James Patterson :)
Artemis Fowl and Dune
As a kid, Harry Potter. As an adult, The Dark Tower.
LoTR and Harry Potter when I was a kid.
But the one that I bought as an adult that really affected me was the Elena Ferrante My Beautiful Friend series. I still think about it every so often and it makes me cry a little. I’m a guy not in Italy and the story of two women in Naples makes me cry, if that’s not art I don’t know what is.
Other than the usual trilogies, The Hitchhikers Guide to the Galaxy. My longest series was The Dark Tower by Stephen King though.
Probably lord of the rings
The robot/foundation/empire verse by Isaac Asimov
Hobbit + LOTR + Silmarillian when I was a kid in the late 70s.
The grisha verse all book including s&b trilogy and soc duology and king of scars
The earliest one I can remember going out and getting as they released was the Wheel of Time series.
Though I definitely completed more series before I completed that one.
