When I'm looking for new authors and books to read I often check the blogs I follow, browse online bookstores or go to my local bookstore. Of course there are some book bloggers that I especially trust when it comes to book recommendations because in the past we had the same taste in books. I also like to read reviews online before buying a book just to check if there are any story elements that I might dislike.
I also trust my mother and sister. For example I planned to read "The Hunger Games" soon but my sister (she just finished the series) told me that the books are not for me. She knows what plots, characters, etc. I enjoy and what I don't like in books. So although many readers love this series I will not read it because I trust my sis.
I'm influenced by my family, other bloggers and reviewers however the one person I trust the most is myself. If I feel that a book might be for me then not even a horrible review by a trusted blogger can stop me from reading it.
Whom do you trust when choosing a book to read?
