A Truly Epic History
Format: Paperback
This book was awesome and went through the history of the people of the bible from the very beginnings. It's a fascinating read using the new chronology, which is backed up with astronomical events and archaeology. It's not an easy read with all the information in it, but it is worth every minute spent reading it. I think anyone who is interested in Biblical history or archaeology would find this book very interesting.

Obvious deduction with roots in both new and old archeology.
Format: Paperback
The Iron Age seemed to have its beginning several hundred years earlier than has been officially declared. That was my assumption after researching for a historical fiction novel during 1750 B.C.E. period. I began the current research in January of 2013. I'm not a archeologist, have no desire to be one. I'm not related to any archeologists. But I respect the the discipline, scholarship and dedication required to be a good one. After a year of research discovery my girlfriend was well versed with my newly formed assumption about the chronology of these times verses the old school beliefs. Referencing some material in this vain of research I stumbled across Rohl's work. To my utter delight I find out there has been a N.C. movement growing for twenty years. Good work and plausible scenarios are laid out for pure intellectual amazement and entertainment for the imagination inside these pages. Buy it now. Enjoy Zak

Really Helpful and Easier to Use Than I Expected
Format: Paperback
I bought the APA 7th Edition manual for my college research papers, and it’s been a lifesaver. Compared to the older edition, this one feels much clearer and way easier to navigate. The full-color layout and the examples throughout really help when I’m stuck on how to format citations or references. I especially appreciate the new sections tailored for students like me—it’s not just for professional writers anymore. Plus, the tips on inclusive language made me think more carefully about how I write. It’s definitely a dense read if you try to go cover-to-cover, but as a reference book, it’s super practical. The only downside is that it’s a bit pricey, but for the quality and how often I use it, it’s totally worth it. If you’re in school or need to write APA-style papers regularly, I’d recommend grabbing this manual. It makes the whole process less stressful.
