8yo son and mom love this book
Format: Paperback
I’m a mom of two boys and one girl. I would first like to address the people complaining about the title saying “for boys.” The author has addressed this too and it’s part of the reason why I purchased this book. Boys are falling behind in school and reading. Not sure why some people are allowed to review these books when they haven’t read them or purchased them. Do your research if you have a boy in your life. I would also like to point out that bookstores frequently have shelves dedicated to girls about strong women, strong girls, etc and yes boys can read books in those sections just like girls can read these Great Battles for Boys books.
My 8yo son loves history and is devouring this book. I highly recommend. This book is really exciting and I (mom) am enjoying it too. We use it for read aloud time and independent reading. As soon as I finish this review I will be ordering more in the series, per my sons request.

Amazing

We love these books! My 14 year old has learning disabilities but absolutely loves history. These have been such a saving grace. He’s been able to read these and truly enjoy reading.

Good buy
Format: Paperback
My previous reluctant reader is now a big reader. This series has helped. Both my boys 9 & 12 have enjoyed this series. Another series in addition to this, if looking to expand once you have all the titles, is Nathan's Hales Hazerdous Tales.

Concise, well researched and objective; a great homeschool resource
This is a great read; sufficiently detailed to be worth the time spent, but not so bogged down in minutia that you find yourself wondering how long the chapter is going to go on and glancing ahead to see if it ends with a quiz. Particularly notable is the prose: flowing, easy to read, a comfortable narrative. You get a sense of the author relaxed in an easy chair, his audience gathered about, attentive ears regaled with true tales of valor, intrigue, and conquest. But you will find no glorification of war between these covers; rather a well-balanced rendering of man at his best within his worst.
“Great Battles” is well researched, factual, and untainted with retroactive speculation and subjective parochialism that pervade some of today’s ‘historical’ accounts. In short, a valuable addition to any homeschool or military historian’s library; highly recommended.

FINALLY!
Format: Paperback
I was pleased to finally find an historical series written for young boys that neither "cartoonizes" war nor adopts a satirical, demeaning tone. Rather, these books depict the true sacrifices of the men involved in these conflicts. The facts are the facts. There is no politically correct hogwash clouding the child's view of the event. These are more mature historical articles about pivotal events no longer discussed in our public school! These books glorify the ideals scrapped by post-modernists -- bravery, chivalry, and heroism -- ideals that once defined masculinity and limited its so-called "toxicity." As a mother raising masculine gentlemen, I will continue purchasing these fine books! Thanks, Mr. Giorello! Keep writing!
