Query: Great debut novel!

What a great read! Any lover of a good suspense novel, full of twists and turns and engrossing plots, will love this one! I loved trying to figure out the killer and trying to tie everything together throughout the story - though I must admit, I came no where close! I cannot wait to read more by this author - he is sure to be one that many will know!
