Jon Land’s kicking off a new crime series with THE SEVEN SINS: THE TYRANT ASCENDING, and we’ve got five autographed copies to give away, plus packs of SEVEN SENS playing cards! In keeping with the thriller’s Las Vegas theme, we’ve got a fun way to find our winners: We’re going to play 21! (Or at least a simplified version …)

Below are five sets of blackjack scenarios. For each one, choose whether you’d like to stick with the cards as shown, leaving the third card unrevealed (”stay”), or whether you’d like to turn that third card as well (”hit me”). The object, of course, is not to exceed 21. E-mail us your choices — “stay” or “hit me,” for all five scenarios, along with your name and mailing address. Those who get the most correct will be in line to win; we’ll announce the lucky ones and reveal the hands on Friday, July 11.
