- Sucked me in!- 5 - By Erniecheese - Great book. Sucked me in. 
- Ellis is good!- 4 - By Bob852201 - The Black Book is well worth the time to read. I doubt Patterson wrote a single word of the story. Take a shot! 
- Just okay- 3 - By Jam's I-phone - It was okay. Very predictable. 
- Fast, Hard Hitting BUT Surprise, Surprise!- 2 - By legaliis - Another Patterson best. The reading chapters are fast so they tend to keep one in suspense. As usual there are little twists and turns but a huge finish that I, frankly, hadn’t seen coming. 
- Great read!- 5 - By Jjwalkingjim - One of his best book!  I was completely surprised by the ending not being able to figure out the outcome prior to it being presented to me! 
- Yhhgff- 5 - By Tuckaseegee Fly Fishing Guide - Great read 
- No wonder James Patterson is the best fiction writer of all times- 5 - By rlamont - The Black Book is awesome, I don’t know how he does it but when I grow up I want to write like James Patterson...end of story!!! 
- Page turner!- 5 - By abadt714 - Great book! Kept me guessing until the end! 
- The Black Book- 5 - By SuperOrangeade - I could not put this book down. It’s 2:09 am and I just finished it. I need sleep! 
- Black Book- 1 - By Rosimom - Could have been a good if not for constant use of the F word.  Garbage .  I quit reading! 
- The Black Book- 5 - By PattieWagon - Fast paced, intriguing and the “Past/Present” flashes are weaved in very well.   Never saw the ending coming but that is the sign of a good story.  Well done, gentlemen.  We can always count on James Patterson to give us a great read. 
- A great book- 5 - By Mhamsad - This book is awesome really, the events were unexpected and mysterious completely, it attracts the reader and it makes the reader feel as he/ she lives within the events. 
- Great Book!- 5 - By Ray7709 - This is one of the best books that Patterson and co-author of the week has written. Great read. You will enjoy this one. 
- Awesome- 4 - By Deishalarae - Loveee 
- Black Book- 5 - By Halsterx - 5/5 stars. Very entertaining. Interesting plot, characters and story telling angle. Several unexpected twists. I have read ALOT of mystery crime novels and rarely give out 5 stars. Hal 
- Black book- 5 - By Gbr1294587 - Thoroughly enjoyed this book! It is well written, has a great steady pace of thrill, and keeps you guessing. I was constantly looking for more precious time to read it longer but savoring it was just as satisfying. I hope to find another Patterson book with the same reward for my time as he has always been a favorite of mine. 
- One of the best- 5 - By Dbmsjgt - This book kept me guessing up until the end. Just when you thought you knew “who done it” it proved you wrong. 
- David Ellis is a better author than James Patterson- 5 - By McZachary44 - Invisible, The Murder House, and now The Black Book. Whenever David Ellis writes for James, the novels are always so much more better than your average Patterson branded book. I highly recommend it. 
- Black Book- 5 - By CannetteW - I kept guessing the ending and I was wrong.  Great read!!!!
