It's only when I came to look back through the books I'd read that I was able to pick out my top choice. And an author I am definitely looking forward to following in the future. My favourite book of 2009 and break out author - Zero at the Bone by Jane Seville. She brought two distinctly different characters to life in Jack and D, and I hope to read more of their adventures soon.
In December I started to read manga for the first time. And my series of the year and books I haven't been able to put down since I got them are the Loveless volumes by Yun Kouga. Look for my reviews of the remaining volumes in 2010.
All that remains to say is Happy Christmas. May Santa bring you lots of books. :)
