Example Input: This book is a very informative, yet easy read about the realities of life and how patterns are repeated sometimes even unknowingly until honestly addressed and changed. That is where the power of this book lies in giving insight, tools, all with a touch of humor to make positive changes of direction in our lives. Highly recommend.

Example Input: I've been searching for a book that really makes me laugh, characters I can relate and enjoy and a story that keeps me interested beyond the first 30 pages. Well, I found it! "Cocktails for Three" by English author Madeleine Wickham had me completely enchanted. I found the three main characters (Maggie - the pregnant one on maternity leave / Roxanne - the dating a married man one / Candice - the trusting and will do anything for a person in need one) all well rounded and hilarious."Cocktails" goes beyond your basic "friends forever" novel and dives into real life problems and the effects those decisions have on you and those around you.I found this book really unique and sparkling with touches of really dark and edgy comedy. A great find! I hope others will discover this secret of mine.
