The Last Confederate

This is the eighth book in the series "The House of Winslow" by Gilbert Morris

A young Northerner, Thad Novak, makes his way to the winslow plantation and is taken on as a hired hand. What caused him to specifically search out the Winslows? Should the young Northerner be trusted? And with young ladies in the home, what are his actual motives? While the Nation totters on the brink of war, both Thad Novak and the Winslows face conscription into fighting for a cause they don't support, and directly against Winslow relatives from the North!

This is, yet again, another great historical fiction book that will captivate your attention quickly, so far I have enjoyed all of "The House of Winslow" series, and I'm looking forward to the rest of them.
I'd say that 13 is a good age to read this book.

The Reluctant Bridegroom

This is the seventh book in the series "The House of Winslow" by Gilbert Morris.

Sky Winslow, the son of Christmas and Dove Winslow, agrees to return East and bring back a wagon of brides to the men in Oregon City. As experienced as he is on the trail, the past hurts of an unfaithful wife and a twelve-year-old son who truly needs a mothers love, make Sky an unlikely person for such an assignment. On the long trip from New York to Oregon, two of the women who join the wagon train will make their impact. Rebekah Jackson, in the hope of finding a new start, is leaving a broken past. Rita Duvall is a dance hall girl who knows the way to break down a mans defenses, even when at their strongest. 

This is a great book and I enjoyed it thoroughly. I personally think that 13 is a good minimum age for this book.   

Unstoppable: Nowhere to Run

This is one of the newest books in the series "The 39 Clues" which is written by authors; Rick Riordan, Gordon Korman, Peter Lerangis, Jude Watson, Patrick Carman, Linda Sue Park, Margaret Peterson Haddix, Roland Smith, David Baldacci, Jeff Hirsch, and Natalie Standiford. 

This book starts with Dan and Amy Cahill at the funeral of their lawyer, when its over, they are attacked and escape getting buried alive. Through a turn of several events, they end up in Ireland trying to crack yet another code. Will they make it by themselves or will they need to call for help?

I love this series, I have read all of them and they never cease to keep me on my toes. I would say that eight is a good age to read these books.
