Thanks so much, Jenna! Part of the reason for the consistent voices and styles comes from the fact that we were all picked in advance because the editors thought our natural writing styles matched -- we've all had lots of experience writing fast-paced action, adventure, mystery books with a big dose of humor. So a bit of that is built in from the start. Also, we each take care to read all the books that come before ours, so we can be sure not to introduce anything jarring or out of character. Beyond that, we all love adding our own personalities, our own brands of storytelling, character development, odd twists, etc. Each of us tends to identify with different characters, too. For some reason, I really connect with the character of Alastair. Gordon likes Jonah, Jude identified with Irina, and Pat enjoyed Hamilton Holt. So we tend to develop our favorite characters and introduce those new subplots into the mix. It gets pretty crazy -- each of us raising the bar just a bit more for the next author ... and making the Cahill story a bit more complex! Actually, we're all friends and we enjoy the challenge. As for the title of Book 7, I have to confess something: I am the world's worst title thinker-upper. I usually suggest dozens of potential titles, all of which are rejected! "The Viper's Nest" was my editor's suggestion, and at first I had your reaction -- hmm, no vipers in the story, really; but then the title grew on me. Dan and Amy are plunging into the heart of the Tomas world, the center of Cahill evil ... a viper's nest! It works symbolically and it has a cool sound. Hope that answers your question!
