Not all of the dates have been revealed and it's possible some will change or are just incorrect. I will update it as new books I'm looking forward to come to my attention and as the dates change or are released. It's very possible I have failed to list some that I wanted to and I KNOW there are some that I don't know about so they are, therefore, not on my list! Please let me know of any books of 2010 that I don't have so I can add them.
They're divided into three different types. New authors, stand alone books, and sequels.
