I love this Langauage arts curriculum!  I found it at a homeschool curriculum fair this last April.  Each workbook focuses on a novel and is about 8 weeks long.  They  cover grammar, spelling, writing, vocabulary,  comprehension questions., and extra projects.  We used the workbook based on the novel "The Whipping Boy" by Sid Flischman.  My 10 year old really liked the story and doing the workbook pages-this is my son who normally isn't thilled with school :) .  I will be using this curriculum with my 11 and 13 yr old boys this fall.
