Module 1 question

Hi. I am new to this forum and to homeschooling. I have tried to post this question a few times:-/ so I am trying again:-) I have read through past posts about finding the Oxford First Ancient history book, but have not been able to find any answers. Is there a replacement for it? I saw About a year ago SCM was trying to see of it could be republished. I am also having trouble finding the mystery of the hieroglyphs, I found one that was $150, however that is not in our budget. Are there replacements for the books or does anyone have any wisdom?? I have tried bookfinder.com but neither title has results.
