Query: Great New Book by Great New Author

What can I say? I loved this book! The characters--gotta love that Tally!--are so well-developed that I probably will find myself looking for them next time I'm in Boston. Great plot that kept me up at night. I kept telling myself, just one more chapter... Dynamic writing, real-life dialogue, a colorful cast of characters, and plot twists and turns that kept me guessing until the very end are just a few of the reasons I've put the next Stiefel book on my "must buy" list.
