Take control of your GM Gen V LT1, L83, or L86 engine with Terminator X!

Raw and Honest
Format: Hardcover
I admit I purchased this book because of all the hype, but also because I have been, since childhood, intrigued by her various family legacies (Burden, Vanderbilt, Cushing, Fairbanks), and their alliances (Whitney, Astor, Roosevelt, etc). I was not sure what to expect, but I am grateful I read this book. Being a queer man I probably am not the core audience for this book, I can attest it is still a great read. Ms. Burden is amazingly candid and honest in a way I don't think most people in her situation would be. I can already tell that there will probably be countless reviews about how privileged her life was even during and after her divorce, and how unrelatable this book is for many people, but then you are missing something. If you want to judge Ms. Burden for things she had no control over then you should examine your own life. My hat off to the author for being so open about such private matters in her life, and also for doing a great job shielding her children in life and in the book. I hope it is true that there is a movie/series being made that will star Gwyneth Paltrow. I love Gwyneth, and if the author won't play herself I think Gwyneth is an amazing choice for her poise, acting ability, and class. Can't recommend this enough! OH, I am curious to know if anyone who read this book read Wendy Burden's memoir Dead End Gene Pool. I LOVE that book, but it is so very very different, and I am curious to know if Wendy and Amanda get along irl.

Daily devotional with ease.
Format: Imitation Leather
This is a great little devotional book for men. I bought two, one for me and one for my son. I keep mine at my desk at work and read it each morning and I enjoy the insightful quotes and verses that help me start my day. It truly only takes about a minute or two to read through everything and the verses are actually written out on the page with the reference. I know there are a lot of devotionals out there that you can select from, but I like this one because it’s small and compact and acutely directed towards men. The small size is perfect, the price is excellent, and the daily devotionals are spot on.

Easy and fun to read! Cute and small, easy to travel with
Format: Imitation Leather
I’m obsessed with this book. Each devotion really does only take a minute to read. It’s compact so I leave it in my truck but sometimes I’ll bring it in and keep it by my bed. There’s a book mark ribbon that keeps your place if you get off track of your days and you can’t remember where you left off. And I also like HOW the messages are explained. I grew up in church and I’m always like “hmm that makes sense now that it’s put that way!” lol

The Answer
Format: Imitation Leather
I purchased this book of Devotions as I was looking for a guide that would be simple to follow and compact. It seemed like I always was making excuses for not being as diligent with my faith. It was easy to tell my self that I could not keep up with God or travel with a guide as it was too inconvenient or bulky. From a content and simplicity to stay focussed, this was the source I needed. From a convenience standpoint, it could not be any better. I had tried apps and digital versions previously and it just wasn't the same. Holding a book and leafing through the pages just feels so much better to me. A definite must for those of you looking for a impactful, yet small and convenient way to continue the journey.
