I picked this one up for free a couple of days ago. I'm reading it right away (not my normal behavior) because the sequel, The Werewolf Upstairs, is also on sale for $2.99. All of this is to promote the author's newest book, the third book in the series, The Vampire Next Door. I don't want to buy the second book without having read at least part of the first one, but knowing Sourcebooks, the sale on The Werewolf Upstairs won't last very long! I'll make my decision tonight.
Take my advice, and if you think this might be something you'd be interested in, download Strange Neighbors now, while it's still free. Sourcebooks is notorious for very short free ebook promotions, and this one may go back up to normal price as early as tomorrow!
