In no particular order:
I read The Harvesting for a blog tour and I'm so glad I did. This is one of my favourite reads this year. I absolutely loved it and if Melaine's first book is like this they can only get better, right? So of course she would make this list.
Marissa Meyer was always going to make this list. I adored Cinder last year and loved Scarlet even more this year. I'll read anything she wishes to write.
Kate Avelynn was another debut author I read at the end of last year that I absolutely loved. Her writing took me on an emotional roller-coaster. I'll happily read other books of hers.
Yet another new author, Alexandra Bracken, I read last year that I loved the writing style and loved the book. I can see me loving anything she puts out.
Stephen King has been a favourite author of mine since I was a teenager. I haven't read everything he has written, but I've read a lot and I'm never disappointed.
Another debut author, Brigid Kemmerer, that I read last year and adored. While I haven't read the second book I have it and I'm sure I'll love it, along with anything else Brigid writes.
I haven't read the Iron Fey series, though I have it, but I loved The Immortal Rules and The Lost Prince. I'm sure when I get around to reading the her other books my view on Julie's writing wont change.
I have loved Sophie Kinsella for many years and her books never disappoint. I read her last release I have your number and it was fantastic. I'll always love her books.
I have read the first two books in Rebecca Lim's Mercy's series and I enjoy her writing style. I have the last two books to read, but I'm sure she wont disappoint.
I have recently finished Pushing the Limits, and Katie McGarry is definitely on my favourite authors list. This book was fantastic.
I look forward to seeing all your answers, and getting to add more great authors to my TBR pile!! =D
