We didn’t see or hear from the other characters from the series in this book. It definitely stands alone. Great story of commitment and survival in a zombie future. Wish I could remember if Malcolm’s family are mentioned in any of the other books. I’m sure everyone will come together at some point so I will start book 5 now. Then on to Sidney’s story and I am really looking forward to that one. She been my favorite character so far.
Andrew is, as always a top notch excellent narrator. One of my favorites!
