Query: Gripping

Rick Mofina has bolted from the starting blocks with this novel. It's an extremely well-written, crime/suspense tale that grips your attention from beginning to end. Mofina's crime-desk knowledge is evident and his writing skills are well-honed; he obviously writes with the reader in mind.The characters are well-developed and the story is flawless. I can't wait for the movie! I hope Mr. Mofina follows up with more. He has definitely hit the mark with "If Angels Fall". It's a must read.
