Technically, the weekend is only part of it. Starting today, CoM: Book 1 is free until Monday. Rather than give you a link on here, look to the right margin. There you'll see a book cover for it that will take you where you need to go. Remember, this book is on Amazon only, and the freebie pertains only to the e-book version. Do me a favor and spread the word, even if you already have the book.
Thanks in advance. :)
