It's Byron Walden week which, as you might have guessed, means the first five-star difficulty puzzle of 2013! This is probably not the hardest five-star puzzle you'll get from us this year, but we think it earns its rating.
In the meantime, just a heads-up that Caleb Madison is currently hard at work in the second sub-basement of AVCX headquarters, working on a 21x21 bonus puzzle that you'll get within the next month. It'll be part of a contest with a prize. Caleb's puzzle will be available for purchase to non-subscribers, but you'll get it free.
