Which is worse: Finding a book you love and then hating everything else you try by that author, or Reading a completely disappointing book by an author that you love?
I really like the question. It's a tough one, for, in an ideal world, we'd be able to have our cake and eat it too. However, as the only thing ideal around here are the thoughts in my head, I'd have to go with "reading a completely disappointing book by an author you love". I'm waiting for the applause from the audience, and my grand prize now...
Let me take a second to explain the why. As in, why I think that's worse.
When a new book is released by any of my favorite authors, I get really excited, and hype it up to be this big thing. I can't wait to run to the store, purchase the book, and then immerse myself in the book completely. And that's mostly because I expect it to be good. How many books by an author would you read, before you'd shortlist the author as one of your favorites? Five, maybe six? If all the books you've read prior to elevating the author to this god-like state have been unputdownable, it's really frustrating when you come across a bad book. But... you know what's even worse? A spate of bad books.
I was a massive Grisham fan. I've read practically everything by him. Then, he came out with the autobiographical A Painted House. Just because it was a Grisham book, I actually read it, hoping it would come good. It didn't. That was then followed up with Skipping Christmas, Playing For Pizza, and Bleachers. That was the end of my Grisham love affair. I know he's published a new legal thriller recently, but... I just can't bring myself to read it. Disappointment with books really get me down.
On the other hand, if you've read one book by an author, and you've loved it, you're tempted to try another for purely exploratory reasons. Does the second book live up to the expectations you had of it, based on the first book? Or, does it make you want to drop it like a hot potato? The thing is, even if the second book is not great, the reader doesn't tend to feel that disappointed. I normally just think: So much potential.
Of course, if the first book by the author has blown the reader away well and truly, it's a dilemma. What if the first book you read was amazing? What if it was one of those that won the Booker or the Pulitzer or something? What if it was, in reality, the author's best work. Are the readers bound to be disappointed then, by reading the author's most popular works first, and then not being that impressed with the next few works? Or, are they just supposed to take it in their stride?

I ordered this book on Amazon, after seeing its name appear on the 
We've all faced the wrath of high school. Either we were too fat, or too thin. Either people expected too much of us, or nothing at all. Either we were 'cool', or we were 'geeks'. Some of us made our peace with it, while some of us still hate that part of our past. Children can be cruel. Adolescents more so. And this book draws on that very attribute of teenagers, to show how harmless 'fun' resulted in a young attractive girl deciding that suicide is her only escape. Thirteen reasons. Thirteen. The Baker's Dozen. And the protagonist is called Hannah Baker.
This is a well-written page turner, with all the elements of a good story: romance, history, friendship, murder, revenge, redemption, bad cop, good beggar, a young impressionable protagonist, and a history that seems to be re-living itself, with different actors...

An anthropomorphic anti-Soviet social satire, this book stirred up a fair bit of controversy, and initially, a multitude of publishers refused to print it, fearing the repercussions of the act.
The book focuses on the animals of Manor Farm, and how they go the full circle, from being owned by men and working for them, to being an animal democracy, and then the balance of power shifting again, to one of the species...
This is The Great Gatsby set in the 21st century, in Pakistan. The similarities between the two books are striking, and the endings are almost identical. In fact, I'll go out on a limb and say that this book was inspired by Fitzgerald's classic.
