The first book in this series, set in the post-Civil War Arizona Territory, finds the five recently orphaned Martin siblings facing a serious situation. Most folks in their vicinity know Mrs. Martin passed away two years ago. They don't know that Mr. Martin is now deceased too. The siblings know they can run the ranch by themselves, but they don't know if they can keep Pa's death a secret. If their secret gets out, the local law will haul them off the Box M and throw them into an orphanage near Tucson. They'll need to work together and trust God to help them if they're going to succeed. Saddle up and ride along with the Box M Gang for an adventure you won't forget!
