It's getting close to the end of the year but there's still time to challenge yourself to read a few more books before 2014 gets here. If you've imported your bookshelves from somewhere else you may have already completed a challenge and you can use books already shelved (as long as the 'Date Read' column has been filled in with a date this year) for this. Any books added to the shelf at a later date are automatically added to your widget for you (just remember to compete the 'date read' bit.)
Lets add a Booklikes Challenge Widget to our sidebar to show everyone what massive bookworms we are :)
