I really loved Latin Road. I had no real Latin background, and when I looked at the other books they looked SO difficult to even START their programs. Latin Road is written by a homeschool mom who assumes you know nothing -- an accurate assumption in my case! I worked two weeks ahead of my kids for the whole year, doing the work before them. The student does copy work, copying off the information in the textbook so they can learn the information slowly as they are writing. Then they do some translating Latin to English and vice versa. Then they do some memorization (FUN memorization, by the way - this Christmas Alex led the choir in Adeste Fidelis that we had learned in Latin.) I also know that Latin Road WORKS. Alex is STILL taking senior level Latin in college, and still getting A's. I know that any mom could teach Latin using Latin Road, provided you can convince your student to do all that copy work.
