CBR has the preview for issue 18 up now. This is the 2nd part of X-23's Misadventures in Babysitting!
Be sure to pick up your copy next Wednesday, December 7th. Tell your friends too as well. Help send a message to Marvel this character is loved and deserves a second chance at a solo later down the line. (Like say a title called 'Exceptional X-23' at a rate that it hits the 23rd issue on October 23rd 2013 that has Craig Kyle on board along with Sana Takeda and Liu among maybe some others that can help bring the best of all worlds out of the character for a better mainstream push...)
While you're there picking up your copy, I highly recommend picking up the first issue of the Defenders. From the preview alone, it looks well worth the read! It's written by Matt Fraction, and has colors done by Sonia Oback, who was one of the original artists on the X-23 minis. (Yes Fraction, if you say 23 often enough, I will plug it... Maybe.)
