This was a rather hard question! After all, authors who are popular with book bloggers right now may not be widely popular but i don't know that is really what the question is after. I am going to use the "everyone" in the question as "other book bloggers". After pouring over my librarything books I'm going to go on 2 different tacks with this question.
Who’s your favorite author that other people are NOT reading? The one you want to evangelize for, the one you would run popularity campaigns for? The author that, so far as you’re concerned, everyone should be reading–but that nobody seems to have heard of. You know, not JK Rowling, not Jane Austen, not Hemingway–everybody’s heard of them. The author that you think should be that famous and can’t understand why they’re not…
So i am first going to talk about a couple authors that are recent but i don't think i've read other people reviewing them.
Susan Hubbard: she's written several books but started her Ethical Vampire series with The Society of S (331 people have copies on librarything) in 2007. I've read that and have the second book, The Year of Disappearances (98 on librarything), on my TBR Pile. I guess this hasn't hit like Twilight because the main character, Ari, is just 13 at the book's start and there isn't a love triangle. Much more realistic portrayal of growing up, discovering yourself, and synthesizing mixed heritage.
Lynn Flewelling: I've read two of her fantasy novels, The Bone Doll's Twin and Hidden Warrior. It is a very rich world that Flewelling creates, with powerful forces against women. Since i've seen lots of people rave over Anne Bishop's books, i don't know why this one with similar themes isn't more poplar. The third in that series, The Oracle's Queen, and the first in an older series, Luck In The Shadows, both sit patiently on my TBR. ok, i really need to get to those soon.
I also want to highlight two classic books that i don't know i've seen reviewed but that i love!
I loved Giovanni's Room by James Baldwin when i read it a few weeks ago so i won't say much more now. Read it! It's a beautiful, tragic love story.
I also think The Lover, by Marguerite Duras, is one everyone should read right now. A short novel about a girl growing up as she has an affair with a Chinese man in the 1930's. Another love story, though less tragic and more dreamy than Giovanni's Room.
any unknowns i need to look up RIGHT NOW?
