I have recommended Schlock Mercenary a couple of times as a webcomic I think you should be reading. It’s the second thing I read every morning after getting on the internet. (The first is the local weather forecast to which my homepage pointer is set.) Howard Tayler’s recent promotion, however, reminds me that you can still get Schlock when you’re not near the computer for some reason.
You can get the comics, plus bonus stories NOT online, in print. Gloriously, Howard has opened pre-orders for Schlock Mercenary: The Sharp End of the Stick. This is the eighth book of the series, so feel free to pick up the previous seven while in the store. If you’ve got the cash I’d actually recommend spending the extra $10 to get the numbered customer choice sketch copy. During the order you pick the character and have the sketch added to your copy.
