Hi there, I am new to this forum, but not new to homeschooling. I have a 9 year old, who attends CC and loves Story of the World. I also have a 15 year old, who I didn't start homeschooling until middle school. He has completed a year of ancients, and is ready to move into the middle ages, which is also the cycle of history that my younger son will be in. I have combed the earth looking for a history spine for my 15 year old to no avail. Biblioplan was dry and choppy, Notgrass doesn't follow 4 year cycle, and most of the other books are boring. It would be nice if both of my boys could follow the same history flow, so that our family discussions can be done together. Any suggestions? Is there a book for teens that is like Story of the World?
