Best arthurian fantasy books according to redditors

Here I was thinking it was Merlin.

"Black Horses For The King" was my personal favorite.

Is it The Lost Years of Merlin by T.A. Barron?

I've read and loved almost all of the recommendations already here (TAMORA PIERCE). But to add some that haven't been mentioned (and trying really hard to not overload you with 20 books at once), I read and reread Robin McKinley's The Hero and the Crown and its prequel so. many. TIMES. Maybe even more than I reread Tamora Pierce. Patricia McKillip, Maria Snyder, Patricia C. Wrede (Dealing with Dragons quartet), Althea Kontis, Francesca Lia Block, Libba Bray and Susan Fletcher (Dragon Chronicles) are similar authors to check out for awesome female-driven fantasy, with varying degrees of lightheartedness. Wrede, Fletcher, Snyder and Kontis all wrote books that lean a little less epic/serious, Block writes a lot in prose that's also a very quick (but more intense) read, McKillip tends to be more wordy but beautifully so, and Bray can kind of go either way depending on the series.

For more contemporary fiction, RACHEL COHN (of "Nick & Norah's Infinite Playlist"). Her Gingerbread series has content a good deal more mature than Angus, Thongs, etc., but her style is similarly irreverent and witty and really fun. Seriously, check her out. Sharon Creech's Walk Two Moons is like a much younger version of Cohn, still zingy and sweet. For a quieter modern-day read, Garret Freymann-Weyr writes realistic (more mature) young adult relationships, and introduced me to the idea of bisexuality in a sort of roundabout way.

Julia Alvarez relates stories about the Latina-American experience incredibly well, although I think the first book I read by her takes place solely in the Dominican Republic. According to my reading list, I guess young me got sick of reading about other white people, so I'll add Marjane Satrapi's hilarious graphic novel Persepolis and the more sedate Shabanu series by Suzanne Fisher Staples.

I'd also strongly second comments for Gail Carson Levine, E.L. Konigsberg, and did I mention Tamora Pierce?

(I tried to link a lot of authors to my faves from their work, but I won't be mad if you never look at any of them. Is your reading list long enough now? Also, I know you didn't ask for a ton of fantasy/historical fiction recs, but I think a lot of us defined our teenagerhood by and identified more strongly with one of those series or another.)

tl;dr my top three recs that haven't been mentioned yet are Rachel Cohn, Julia Alvarez, and that one duo by Robin McKinley.

Sorry to keep giving the same authors over and over it seems but when they are this damn good and fit the subject so well how can I not.

I give you Piers Anthony and Firefly If it is sexual in nature you can find it in this book. Throw in a monster that feeds on sexual energy and people and you have a great book.

For some just outlandish sex and fun by him I also give you Pornucopia and The Magic Fart

If you want a bit more fantasy to go with your sex there is the little known book 8 of the Incarnations of Immortality Under a Velvet Cloak

Wolfsangel is pretty sweet. It's about the human avatar of the Fenris Wolf (technically that's a spoiler, but you find it out early on enough that it's not a big deal to tell you), and it's the first of three books.

There's a series called the Half-Elf Chronicles. I can't recommend it simply because I haven't read it yet, but might be something for you.

Could it be The Merlin Effect by T. A. Barron? I'm not sure about a light (I think there may be something about one... but I think it was from the treasure itself...) but I do know they get sucked into a whirlpool although not into a different world, instead they find Atlantis. I may be a bit wrong since it's been a long time since I've read it.

Show this gift some love.

As soon as I found out Piers Anthony wrote this 8th book to the incarnations to immortality series I have been wanting it - no matter how crappy the reviews -

But for some reason no one wants to get it for me - and I haven't found it locally!
